Mine's under the hood. Window ECU is behind glove compartment.

 

On the inner fender? only black cover on that side is the fuse block. They must have moved it at some point.

 

the rave has 4 listed tdi, mfi-t16, mfi-v8, sfi-v8

sorry cut and paste from rave is funky

 

sorry didn't mean to hijack, but I've been wondering that. I guess I'm just lucky, my ECM will stay dry with my feet.

 

I had thought I saw mine under there too, but I haven't checked the under hood location so maybe I am mistaken. anyways the power for the OBD2 connector is from the security module, I am pretty sure everything else is either direct grounds or ECU wires. I would check power and ground on the connector first. When I first bought my truck the security module fuse was removed (aftermarket security was installed) and I had no power at the OBD2 port, I wired power directly to it, then after reading the rave manual schematics I found and repaired the actual problem.

 

I have power at pin 16 as well as grounds on 4 and 5. I also verified continuity between the white/green and white/pink wires between the obd connector and the ecu plug. I even tried another ecu but, still the scanner wont read. I am more than desperate right now.

 

Bump!!!

 

my only thoughts would be to check the plug itself, could it be damaged somehow so that connections aren't being made? other than that checking each individual wire.

another thought, drop power down from the switch like I did, I have seen instances in the past where power displays on a meter but disappears once it is called upon. maybe a back feed of some sort.

 

If you tried a different ecu all-together, and it didn't work, I would say has to be the plug or wiring between the ecu and plug.

 

the 2 grounds you checked are different grounds, one is a signal ground (kind of like the negative side of a speaker) and the other is a chassis ground. if the signal ground is touching the chassis ground this could cause a problem.
