My question is, has anyone had any luck replacing any kind of ecu with a used one? Do they last? Does anyone think i should just have an aftermarket alarm and lock system and not worry about the factory stuff. I think this would be cheaper, but I am really looking for reliability. One last thing, where can i get wiring diagrams for my 96 se7?

Traced it down to TWO blown fuses in the panel under the dashboard; the alarm ECU was not getting power for the circuit that drives the locks. My guess is some of the locks is sticking, resulting in larger current draw and a blown fuse. Consider replacing one of these fuses with a circuit breaker - since I've fixed the bug in mine, the alarm and door locks were okay. peter   Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 907 Registered: 09-2002 Posted on Monday, July 21, 2003 - 01:32 pm:    btw, obviously, replacing the alarm ECU with another one didn't change a thing.   Mark Groenda (Mhg9797) New Member Username: Mhg9797 Post Number: 14 Registered: 07-2003 Posted on Monday, July 21, 2003 - 02:08 pm:    Thanks peter, The fuses i have checked are in the panel under the steering wheel, and i only see one for the alarm. Are there others under there somewhere? I am also worried that replacing the alarm ecu will be a waste.

The alarm box gets power at two of its pins, and the power comes from two different fused circuits in the panel. I don't have Rave here and don't remember which fuses to check, you could check them all if you wanted to. Just FYI - every other time the truck wouldn't start; I had to dis - and reconnect the battery to fix that. My wife wasn't happy to have to do it once or twice a day   Mark Groenda (Mhg9797) New Member Username: Mhg9797 Post Number: 15 Registered: 07-2003 Posted on Monday, July 21, 2003 - 04:36 pm:    Where is a good place to pick up a Rave CD?   Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 910 Registered: 09-2002 Posted on Monday, July 21, 2003 - 06:51 pm:    well... strictly speaking, I don't think it's legal. check the archives
