Engine/Transmission (1994 - 1998) electrical question

[krohn]

Hey guys, I was wondering if any of you know what wires on the loom hook up to the starter relay in the fuse box on the drivers side wheelwell of if there are any wiring diagrams available. My truck caught on fire and I really have no idea which wires go where. There are tow heavy guage wires with eye connectors and i think one has two smaller wires(orange and blue?) and the other with blue green. I want to do it right so i dont smoke the ecm, or any other damage. Any help is much appreciated

You REALLY need a service manual. It has all the circuits.

Thanks for the info, does Chilton or Haynes make one?

I can't help with the '95 service manual, but I think I can walk you through determining which wire is which.

Of the two heavy wires, one should have B+ voltage on it, routed through a fuse (#2, 30A on my '98); this would connect to relay pin 30. The other should show zero voltage (goes to the starter itself), but perhaps 100-200 ohms of resistance; this gets connected to relay pin 87.

Two other lighter-gauge wires also connect to the starter relay. One wire should be connected to ground; it will connect to relay pin 85. The other lighter-gauge wire should show no voltage normally, but would show B+ when the key is in the start position and the clutch is depressed; it will connect to relay pin 86.

Good luck, and I hope the fire didn't release *all* the smoke from the truck.

Thanks for the rundown Fest3er, that pretty much sovled my problem. Much abliged. I will work with it tomorrow after my last run of parts.



thanks, Krohn
