TurboDoorHandles Posted September 8, 2010 Report Share Posted September 8, 2010 Anyone know what the heck this is? It seems like some kind of fcd or something, btu I have no idea. Plugs seem factory, but it definately isnt anything I've ever seen on a sq http://nwstarquest.com/83mysteryharness.jpg Link to comment Share on other sites More sharing options...
shoquest2007 Posted September 8, 2010 Report Share Posted September 8, 2010 I may be wrong, but I beleive that was a harness that delt with the injectors on the 83 models. The harness was peice you show was added as a fix. I again am not a hundred percent sure. Link to comment Share on other sites More sharing options...
TurboDoorHandles Posted September 9, 2010 Author Report Share Posted September 9, 2010 I really won't have an idea what it does until I get a ecu pinout. I can't find any Mitsubishi markings anywhere or even a pn the wires are also not color coded Link to comment Share on other sites More sharing options...

Factory issued a patch harness to solve the problem. -Robert Link to comment Share on other sites More sharing options...
Indiana Posted September 12, 2010 Report Share Posted September 12, 2010 They did a TSB mod that put a modulator under the dash near the ECU that limited the TPS voltage to only 3volts. It had something to do with driveability. I can get you the TSB if you like. Link to comment Share on other sites More sharing options...
