82 Carbed Conversion
What is the best way to get water temp gauge and electric fans to work. I bought the car with blown motor and coffee cans/5 gallon bucket of parts. It is running now with ecm unplugged but efi harness still intact and tucked away. Fan wires are hooked up and original temp sensor in thermostat housing. I am a corvette person and due all my own work. Also no headlight operation (vacuum lines look good, all hooked up, have tried pulling vacuum from intake and carb with no luck, also have tried overide). Thanks, Mark

i also have a carb on my 82 so i can help you.
1. the water temp sensor for the gauge is on the front left (driver side)
head. it has a wire coming out from the fender by the alt to connect to the sensor in the head.
2. my 82 only had 1 factory electric fan and is controlled by a sensor in the rear right (pass side) head. all this sensor does is ground the fan when the temp rises high enough. i kept mine pluged in but also T the wire coming from the fan to a switch then to a ground. so it works like factory or i can hit the switch and turn it on when i want.
the headlights i can't help you. mine work and i never fooled with them before.
hope this helps.

If its the original with the TBI's you probably have a massive vaccum leak in the top plate they sit on or the one way valve on the brake booster is bad.
If its an engine other then the Crossfire I can't help.

It is the original block, with better crank, rods, forged trw flat tops and a small cam ( straight duration 214 and lift 445), ported 441 casting heads with screw in studs and guide plates, torker II intake, accel hei, edelbrock 1405 carb. Motor pulls good vacuum.

GS977, Thanks. I will pull sensors out of old heads and be good to go. What kept throwing me off was a sensor coming out of the thermostat housing (1 yellow & 1 black pigtail). Possibly a housing off another engine or a production change. I do have a green wire on driver side and a blue/black on passenger side for the sensors.
