Removing the FI harness after an engine fire but have some questions.

At the firewall in the engine bay the massive harness splits off twice, once to the dropping resistors (removing) and agin with 2 wires that go to the batt neg and pos cables, do I have to seperate those from the harness and keep them or do they go also. And I assume that the only thing under the dash that goes is the big plug to the ecu?

At the same time it looks like the only other wiring affected (melted) is the wire to the temp sensor in the thermo housing and the wire to the brake proportioning valve sensor, are ther anything special about these wires?

Thanks in advance guys!

The FI harness is one complete assembly. Everything goes.

There is the FI Relays and also a 6-way connector on/near the steering column.

Temp Sensor goes to Temp Gauge in dash. Brake sensor goes to brake light in speedo. In addition, there is a major ground that connects to the cable clamp that the FI harness feeds through on the manifold, in addition to a ground wire that fastens to the strut tower w/ the FI wire clamp.

You also may want to pay particular attention to the wires @ the coil, and also the pair of wires going from the 'patch panel' (green and red wires) to the pick up coil on the distributor. The A/C control may also be affected as well as the BCDD control wire.

How major of a fire? It seems as though the whole body harness (inside the engine compartment) would be compromised.

Have you downloaded the wiring diagram (see post #13) posted?

I attempted to take some pictures, but unfortunately my camera wanted to put extra flash on everything, so that was a wash...

got pretty lucky, fire was centered under the middle carb, like I said only the 2 sensor wires other the the FI harness, quick reactions and a full fire ext at the place I pulled into!

What was the cause of the fire? Good thing you extinguished it quickly. An onboard extinguisher should be on your shopping list also.

Trust me it will be! Best guess is a carb float stuck??? Dont really know but aint much in that area!
