First let me say Thanks to all the contributors! I've found a ton of useful info here.

Unfortunately, I've found some conflicting info on the location & type of my cooling fan relay.

I have a 1987 Carbed 305/5.0 iroc. There are some relays on the firewall near the brake booster. They are too cooked to ID by part number. I think one is the spark control. The most fried one might be the fan relay but only the top and mount tab remain. The car is Carbed and has a mechanical fuel pump so I have no idea what the third relay is. The fourth looks a lot like a map sensor and even has a vaccum hose. But there is another by the a/c condenser with a vac connection but no sign of a hose anywhere near it.

Worst of all, the connectors are all gone / melted.

Assuming the reason for the melt down is related to the missing fan I replaced, is it safe to say a fan relay was involved? If so, can anyone tell me what wires go where - specifically for the fan relay if nothing else? The wire colors coincide to the fan circuit but I've not been able to find a diagram that shows where they go on the relay.

Pics would help a lot but any advice will be greatly appreciated! I managed to find a low miles, rust free 87 in Ohio - the next miracle will be getting it right!

 

I think '86-87 LG4s had the low pressure electric boost pump in addition to the engine mounted pump;there might be a fuel pump relay.The map sensor looking device over by the A/C is the barometric pressure sensor-there is no hose connected,but originally there was a little foam filter on the hose nub.

 

Thanks to you folks, whoever posted the various wire diagrams, and a donor harness, everything is working again. Much appreciated!
