Gauges arn't working!
 

I just did a engine swap, and none of my gauges aren't working. Battery gauge, water temp, gas gauge, and i cant find the wire for my oil selonid. any help of wire diagram or pics of the wires would be great. And yes my water temp wire is hooked up.

What are you driving?

Have you checked the 'gauges' fuse?

1986 k5 blazer w/ a 350 out of a 79 k5 just swapped out last week everything is connected like it should be. none of my gauges are working and i cant find the oil solenoid wire

You really should check your fuses. The gage/idle fuse (20A) drives pretty much the whole cluster.

As far as the oil pressure sending unit wire, it should come out of the wiring harness that crosses over the top of the engine mounted to the firewall. It should drop down to the sending unit which is located on the back of the engine between the distributor & the brake booster.

I cant figure out which wire it is. I have a lot of extra wires hanging cause i did just a basic swap. I took out the ac, cruise control, and smog pump.

Ok, The fuse was blown. I put another one in and it blew immediately. Bad ground maybe, or what?
