Integrated Module

stimpy · 12-29-2003, 01:59 AM

For those who have done a USDM swap, what exactly is the integrated module used for? Is it only necessary for the security system or must it be retained for some other function? I accidentally clipped the backup light wire that goes to the integrated module from the transmission cord and I'm trying to find out if I can just tap that wire into my existing car's wires or if i need to push it down to the integrated module like it was before.

Its for the rear defrost, dash lights, etc. Its like a mini-ecu to control misc functions.

I'm not sure how much of the Wrx harness you are using back, but the the majority of the wiring used should be just for the engine only.

All functions unrelated to the engine are being handled by my existing wiring. I would imagine I can bypass the integrated module then and use the older technology for running things? Rear defrost, for instance, should have its own little circuit that is already bypassing the integrated module. Dash lights the same. Backup lights are also the case, however I just need to merge my WRX stuff into the older wiring and that should work.

Yea, just check out the L's wiring diagram for where the signal wire for the backup lights was and tap the WRX's wire into that. Make sure to check the grounds too when you're integrating the harnesses. I remember there were a few that I had to reground because the L's wiring was nolonger connected to the ECU.

I will guarantee that the Integrated Module is not needed on an L
