PorkchopSandwiches Posted June 26, 2014 Share Posted June 26, 2014 Welcome to the forums. The mod is simple and makes a big difference. Install an interrupter switch if you want to turn it on and off Link to comment Share on other sites More sharing options...
mnstrmech Posted June 26, 2014 Share Posted June 26, 2014 I did it to my 93 and love it. Dont have any pics I just copied and pasted what i said on the first gen area. just for fyi it was quite easy.... the "manual" button conversion i did a while ago is easy too. On the TCU module (under the dash, just next to the steering column), the one 20pin connector thats closest to the front, pin 6 is a blue w/ yellow stripe, that is the "manual" control. I snipped that wire, left at least 1 inch on the pin, and the other side of the wire i connected to a relay to turn the ground signal (which the other end of the blue\yellow wire runs to the switch, which goes to ground) into positive voltage. take the switched side of the relay that is positive and tap into the wire for the torque converter wire... which i believe is the red/yellow??? Dont quote me on that... right now its COLD.... WINDY.... and RAINY..... lol...... I should do a schematic for this.............................................. ... "power" mode is easier.... i took the pin from pin 6 (the short 1" blue/yellow wire) and put that two spots over to pin 4... ran that to a switch that the other side is ground... so flip the switch... that pin see ground.... and power mode is active...... VOILA'!....... lol.... BTW.....IF you do the TCC switch mod..... DO NOT TOUCH THE "MANUAL" BUTTON ON YOUR SHIFTER TILL YOUR AT LEAST 40-45MPH!!!!! once you push the button... the TCC will kick in... and the amber "manual" light on your dash will light up.... I did this mod cause i drive on the highway about 20 miles one way to work, and i noticed the rpm's run about 2700 or so at 65... then when i was about to get off the highway... it was 2200... so i researched and found the tcc doesnt get locked up till it hits a certain temp,,, KILLING mpg.. so i went from approx 17/18 mpg to 25mpg by kicking on the tcc as soon as getting up to speed on the highway...... just got to remember to turn off the switch before slowing down on the ramp....... if ya want pics... gonna have to wait... were getting the effects of sandy here in indiana now..

Zues Marine Posted June 26, 2014 Share Posted June 26, 2014 No 'manual mode' button in the 2nd gens^... Link to comment Share on other sites More sharing options...
mnstrmech Posted June 26, 2014 Share Posted June 26, 2014 'Manual' button is for Torque Convertor Lock up control. My special mod. Link to comment Share on other sites More sharing options...
PorkchopSandwiches Posted June 26, 2014 Share Posted June 26, 2014 I've heard that we can make a 50/50 front/rear switch for these cars so we'd have the same power split as the manuals. Any more info on that? It would be pretty fun in the snow. Link to comment Share on other sites More sharing options...
diesel2wd Posted June 27, 2014 Author Share Posted June 27, 2014 ok, so I found some pictures of which connector and which pin to use, this mod is by far the BEST bang for the buck so far! cause it was FREE and its awesome. Link to comment Share on other sites More sharing options...

Zues Marine Posted June 28, 2014 Share Posted June 28, 2014 someone wrote up a mpg comparison between the mods a while back too Link to comment Share on other sites More sharing options...
camroncamera Posted June 28, 2014 Share Posted June 28, 2014 I calculated mileage for the last few tanks... I confirmed that I lose ~1-1.5 MPG with Power Mode engaged vs. stock 4EAT under normal driving. Not too big a difference. Nice to have the extra RPMs on tap when getting onto the uphill highway on-ramps. Link to comment Share on other sites More sharing options...
