BAC5.2 Posted September 21, 2011 Share Posted September 21, 2011 Good plan. You can buy those fancy connectors that they used for pennies from Newark.com, if you want to have a nicer looking harness.

Subimods Posted September 21, 2011 Share Posted September 21, 2011 Alright, if anyone has a set of hella horns, referance your installation guide included with your horns you will see that our harness mirrors hella's wiring diagram exactly.

ShadowImg Posted September 21, 2011 Author Share Posted September 21, 2011 Going to disagree. If you look at the pictures of the harness in the first post, and the harness I returned to you, you'll see that pin 30 of the relay is connected to the stock horn signal. Hella diagram: Pin 30 should always be sourced from the fused battery connection. Link to comment Share on other sites More sharing options...
Subimods Posted September 22, 2011 Share Posted September 22, 2011 We tried to have you give us a call so we could further discuss this, is there any chance of that happening? Link to comment Share on other sites More sharing options...
ShadowImg Posted September 22, 2011 Author Share Posted September 22, 2011 Sure -- I work 6am - 6pm most days (central time). I just got home tonight, but I'll try to give you a call sometime if I have a few minutes. Link to comment Share on other sites More sharing options...
meier motor sports Posted September 22, 2011 Share Posted September 22, 2011 should have just grabbed some parts from autozone or whatever and wire it up yourself. i had wired up air horns to my car. to bad the pos pump took a shit as i expected it would. was fun while it lasted.

ShadowImg Posted September 22, 2011 Author Share Posted September 22, 2011 So I spoke with Subimods wiring guy. Personally I'm going to assume these are just a mistake on their part, but they're claiming it's because the pin orientation on a 4 pin relay vs a 5 pin relay is different. I don't have a Hella 5 pin relay, so I can't comment. The relay I have is 4 pin, and the harness connector is clearly a 4 pin. As far as I am aware, automotive 12v relays, 4 pin or 5 pin use the same basic pin orientation. The problem I had is that pin 30 and pin 85 are swapped. If you have a 4pin Hella relay and a Subimods harness, you should check this. If these are swapped, you need to fix your harness or have Subimods fix it. It will be wired incorrectly and you'll be feeding up to 15A (Hella's rating) through a 7.5A fused stock wiring circuit. They were apologetic and helpful, and hopefully based on the harness I sent back to them they can figure out what's going on. Hopefully they get it all straightened out.

20lgt06 Posted September 25, 2011 Share Posted September 25, 2011 is the relay needed? on my old wrx all i did was use a bigger fuse and it worked perfect Link to comment Share on other sites More sharing options...
ShadowImg Posted September 25, 2011 Author Share Posted September 25, 2011 Well, there will be a stock relay and stock wiring along with the fuse. That wiring/fuse aren't rated past the load of the stock horns, which is less than 7.5A. Hella is indicating that you should provide at least 16A capacity to the supertones. In practice it may be OK, but it's incorrect to run higher amperage through the stock system, and it isn't designed for it. Link to comment Share on other sites More sharing options...
Thorn333 Posted September 27, 2011 Share Posted September 27, 2011 Hella moved to using a standard five pin relay in their kits so the diagram of the five pin relay above is correct however on the older four pin Hella relays numbers 30 and 86 are swapped. I went through this with Subimods a little earlier this year when Hella first made the swap and have bought a few since for friends and my gf's LGT. The only thing that needed to be changed (for a 4 pin relay) was swapping the wires that went to pins 30 and 86 (blue and black) Here is a diagram of the instructions that come with the horns http://img845.imageshack.us/img845/4687/20110927094244313.jpg If you look and follow everything back (I opened a harness to take a peek) they follow diagram 2b exactly with the only difference being they ground the horns and relay together instead of going to two seperate chassis grounds. I see where you may be confused but it really is that simple Link to comment Share on other sites More sharing options...
ShadowImg Posted September 27, 2011 Author Share Posted September 27, 2011 They apparently also have a standard 4 pin, as the relay I got from Hella is a 4pin, wired standard DIN style as above. So it sounds like there are at least 4 options from Hella relay wise. The harness above is wired for a non-standard 5 pin. You are saying they also have a standard layout 5pin. I have a standard layout 4pin, which doesn't match their non-standard 5pin harness. You also say they have a non-standard 4pin. It would probably be a good idea for them to list out relay part numbers the harness is compatible with based on this. That's a lot of possibilities.

98legacywagon Posted September 27, 2011 Share Posted September 27, 2011 I bought there harness last year and it was completely wired correctly I've had no problems at all. Nicest hella harness I've seen. Link to comment Share on other sites More sharing options...
BAC5.2 Posted September 27, 2011 Share Posted September 27, 2011 You wouldn't know it was wired incorrectly unless you specifically looked, that is the point of this thread.

98legacywagon Posted September 27, 2011 Share Posted September 27, 2011 I did look at it why do you think I posted Link to comment Share on other sites More sharing options...
ShadowImg Posted September 27, 2011 Author Share Posted September 27, 2011 Yeah, after talking with them, I'm fairly confident they aren't wired incorrectly for all varieties. Thing is, they are incorrect for the ones I ordered recently. I'm pretty sure I'm not alone in the vendor I got them from, so I'm pretty sure other people have the same issue. *I* don't know all the variations in Hella's relay usage with the Supertones, but something that I think Subimods should be tracking and accounting for. However, they aren't -- so caveat emptor -- and the above information is how you can verify yours. Link to comment Share on other sites More sharing options...
mr.hicksta Posted September 27, 2011 Share Posted September 27, 2011 Wow good find ShadowImg! I got my Hellas and the Subimods relay over a year ago. While I've never had any issues, I'm definitely going to check my relay when I get home. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted September 27, 2011 Share Posted September 27, 2011 This is why I just wired my horns according to the relay I had.... I know how to install a relay so the basics were not hard to figure out it was just making sure that the relay in hand you know which blade is "Switched" and which is doing the "Switching" Link to comment Share on other sites More sharing options...
BigBlack-V Posted September 28, 2011 Share Posted September 28, 2011 once again my hella's stopped working this morning. I am not sure what is happening I do have the Subimods harness & hella relay (4 pin i believe) so I need to look at them when I get home. I am very bad with wiring so if one of your wiring experts could PM me a contact # when i get home later I def could use some help. ShadowImg i sent you a PM I was 0. And I'm still a zero.

BAC5.2 Posted September 28, 2011 Share Posted September 28, 2011 Why did they stop working? Did you blow the stock fuse? I posted the wiring above, just follow that. Do you have a multimeter?

ShadowImg Posted September 28, 2011 Author Share Posted September 28, 2011 From what he PM'd me, I'm going to guess he does not have a multimeter. Sounds like he's had his relay fail. I don't know how relays are rated in duty cycle for having the coil constantly energized, though I'd imagine it's not ideal. Somehow I suspect he actually just needs some dielectric grease, as he didn't apply any during the install. Suspect he'll know a lot more when he pops the relay off the harness connector and has a look. Link to comment Share on other sites More sharing options...
BigBlack-V Posted September 28, 2011 Share Posted September 28, 2011 No I do not have a multimeter however I just spoke with Calvin at Subimods and im gonna swing by the shop today. Its only like 10 minutes from my work so he said he would look at it for me so Im not scratching my head for an hour later tonight. I was 0. And I'm still a zero.

BigBlack-V Posted September 28, 2011 Share Posted September 28, 2011 I just got back an hour ago from Subimods and I want to thank Calvin and Nick for helping me out. I am not technical at all regarding wiring and or how the relay should work ect but its fixed now and working properly. I was 0. And I'm still a zero.

BigBlack-V Posted September 28, 2011 Share Posted September 28, 2011 What was the problem? Without getting technical because i have no clue what im talking about the relay went bad however I am really unsure how or why. If Nick from Subimods chimes in I am sure he can explain it better. I was 0. And I'm still a zero. Link to comment Share on other sites More sharing options...
Subimods Posted September 29, 2011 Share Posted September 29, 2011 CT08Spec.B, your relay had corrosion on the prongs, I would recommend die electric grease on the prongs and setting it up the way we explained. Link to comment Share on other sites More sharing options...
