1980 P-30 Ignition wires?
« on: June 25, 2010, 08:09:36 pm »
Can someone point me in the right direction here. I have a 1980 P-30 Chevrolet Box truck and the previous owner cut the ignition wires at the key switch and installed some aftermarket type of key switch. I have a new key switch for the truck and the correct plug that plugs into it. The problem is the colors of the wires do not match up correctly. I need a wiring diagram for this P-30 Step Van so I can hook it up correctly. Anybody know where I can turn?????? Thanks in advance for your help.

I would suggest you get a service manual.

I agree with a manual. How many wires are there, and what is each color? Include the color of the stripe, if there is one. Also, look at your starter and see what color wires are going there as well.

I too would like a manual, just don't know where to find one.

The problem is the wires in the harness do not match up to the plug that was left in the truck(assuming it was the original that was cut off). I got one from an earlier step van and those colors are different also. So a diagram would show the pin out of the plug, I hope.

How many wires are there?  A service manual would be nice, but with a multimeter I would think you could figure it out.  There should be a wire hot all the time, a wire that gets 12v in the acc, on, and start positions.  Using the existing switch as a guide with a meter, you should be able to track down which wire goes where.  If I was into my column I'd take a picture for you to show the colors.

We you can't call them. You have to send an email. I did that and have got no response from them at all. I sent a second email today......

I have a set of Mitchell manuals on CD Rom, I will look to see if they list what you are looking for...

My manuals on CD-rom only go back as far as 1983, sorry.  My old desktop was not being very nice and froze up... It is only 105 degrees in the garage, can't imagine why it did that...
