Zero1 Posted November 28, 2015 Share Posted November 28, 2015 After searching high and low (and setting a fair amount of money aside) I finally found the gauges I'd been after for years to match the 08/09 dash cluster perfectly. I chose the Defi Advance CR 52mm 2 Bar Boost and 10 Bar Oil Pressure gauges along with a Zeitronix 52mm combination slim fit digital gauge that will show EGT readout in the center along with a sweeping dial for the AFR. To start with the sensor install is straightforward and goes as such: Oil Pressure Sensor - I purchased a Greddy Oil Filter Sandwich Adapter and used it to run my sensor off of. You can also use the galley plug that's nestled under the intake manifold as well. I ran the signal wire along the sway bar passage and secured enough (along with enough slack) to allow for no binding or getting caught up on any other moving parts leading up to the battery area. Boost Sensor - I have a bit of a different setup but typically using a T-fitting to tap into the vacuum line between the intake manifold and the fuel pressure regulator is the simplest solution. I then zip tied the sending unit to the firewall just behind the brake master cylinder before running the wires down to the battery area. Wide Band O2 Sensor - I used the top bung on my downpipe and ran the sensor wire along the top edge of the firewall to the brake master cylinder area where it connects into the harness that I ran parallel to the Boost Sending Unit wire towards the battery area. Exhaust Gas Temp Sensor - I had a bung welded onto my twin scroll header coming off of cylinder 4 to affix the sensor and then ran the wire up to the battery area. The next part is where the work comes... I dropped the fender liner and pulled down the mounting bracket for the main wiring harness where it passes into the left front of the car and into the cabin by the drivers feet. After opening up the bracket for the main wiring harness and looming all the new wires I ran them in the bracket before placing the main harness back into the bracket. I cut a slit using a utility knife in the large rubber grommet where the harness enters the cabin and ran my wires through (I also ran a battery power wire through there for my fuel pumps I have also rewired).

Zero1 Posted November 28, 2015 Author Share Posted November 28, 2015 After getting the wires run I spent quite a bit of time searching for a good mounting place for the control units. I had to be attentive to the limited amount of wire from the gauges themselves as well so I settled on making a spot work and work for both of the control units. I heated up a utility knife blade with a propane torch (please be very careful doing this if you do lol) and very carefully shaved all but the lower tab on the relay panel next to the fuse panel on the bottom side of the dash to act as a vertical support for the control units. Since I could only find one viable location for the control units I used 30lb 3M Double-Sided tape to affix the Zeitronix control unit to the Defi control unit and oriented it so that both units had their power wire connectors facing toward the rear of the car. I also used the same tape for padding and laid 3M Felt tape over on the other side of the Zeitronix control unit in order to protect and dampen from where it rests against the metal framework of the dash. After prepping the control units I set them in place and used three zip ties in sequence to wrap the control units securely to the relay panel careful to avoid smashing any other wires.

Zero1 Posted November 28, 2015 Author Share Posted November 28, 2015 Now for the power wires. Since I am not using any of the other datalogging functions the Zeitronix unit is capable of, I only needed to use the IGN positive switch (red) and GRD (black) wires for the EGT and AFR gauge. I soldered the IGN positive switch (red) from the Zeitronix harness and the IGN positive switch (orange) from the Defi harness together and then soldered the GRD (black) from each into an eyelit connector. I used a double tap fuse connector for the three power and switch wires and tapped them into the corresponding locations on the fuse panel. Connections go as follows: IGN -> UNIT IG1 GRD -> Ground on dash frame bolt (Defi only) B+ -> UNIT B+ ILM -> ILM I also fed the datalogging cable for the Zeitronix unit up into the cavity just under the left side vent to allow to pull out the side panel and hook up to a laptop on your lap.

Zero1 Posted November 28, 2015 Author Share Posted November 28, 2015 Lastly will require programming the gauges but that should be pretty self explanatory with the manuals. Here's a couple pics of a daytime readout vs a night time readout (with lights on). Hope this helps since I wasn't able to find much in the way of write-ups on this before Link to comment Share on other sites More sharing options...
Lathony Posted July 23, 2016 Share Posted July 23, 2016 Your tripod stand, what was the size to fit the defi's 60mm? 58mm? Link to comment Share on other sites More sharing options...
