Wire harness

Does anyone know if you can put a 66 dash harness in a 65. Removed a dash harness sometime back and now can not recall whether the donor truck was a 65 or 66. It was during infant stage of junk yard scavaging. Will deny posting, but to this day have a cruisematic tranny thinking i pulled a C6.


Any input would be appreciated,
dave

I am most certain they are twins as the C/C harness plugs into both and the wiper is alone of main harness and 65 has seperate washer pump harness....whats wrong with the original 65 harness ????

If you need any pointers, give a shout as I got em both here....loose 66 harness too to steer ya if needed...

Thank you cs65, may take you up on that. There is a circuit not sure about. Appears to be factory splice with 2 sets 1 black wire and the other is blue/white tracer with black sockets for light bulbs. The splice also has a single blace wire that has an eye connector. It appears they go to the outter gauges. Could not determine from the wire diagram, finding there are a number of different combinations depending upon type of instrument cluster. If not familiar to you, not a problem. Intend to feel the harness back abit and trace the circuit. Should be able to figure it out.

Thanks to all for the input.

Dave,
It sounds to me like you have just located extra dash illumination wires in the loom. Do you have a "Custom Cab" interior & dash?

Just ordered the taillight harness for the 65. According to the sales person, there are only couple of wire harness that are different between 65 and 66, and one of them is the taillight harness. So i ordered the harness for 65 and either will keep it or send it back for the 66. Would seem if all the engine harnesses are same then except for instrument and accessory variations, the dash harnesses should still be interchangeable but never can tell.

jbridges, certain you are right. Should have indicated the color code was blue w/ red tracer which according to wire diag. is for the instrument lights. As you indicated, the black light fixtures must go to the to the far left and right instruments. There is a black wire to both light fixtures to complete the circuit. There is a splice off the black wire i assume has something to do with one of the outer gauges, alt, or oil. Really closs to completing the dash installation.

The truck is standard cab. Purchased an instrument cluster w/ same round speedo, but included the outer gauges. It has been some time ago, and cannot recall where obtained the harness.

thanks to all for input,
dave

Dave, As I recall the blue/white wire is one of the out board sockets like used on the C/C truck. The socket should have a part tag on it which makes it its own sperate part...it plugs into main harness...round connectors. I will go grab the extra harness and scope things out a bit....one thing I have discovered is the standard cluster setups didnt have the junction block on RH apron near starter relay....The extra harness,less battery cable feeds the alt gauge on the C/C trucks....I have entire fwd harness....under hood as well for 352.


Drop me an email if ya wish....

happy july 4th all.... cs65

jbridges, and cs65, really appreciate the help. As you have indicated that circuit is for the instrument lights for those 2 outer gauges. Was not able to get them to work until this afternoon i gounded the lone black wire that is spliced from that circuit and they now work. Tomorrow intend to spend what ever time nec. to complete and install the instrument cluster.

As for the 'alt' gauge, as best as i can determine, will need to have a separate circuit installed. Once get truck on road, intend to have electrical checked by automotive electrician and probably have them install the altimeter circuit.

cs65 was holding off on email until received the cd 'red book'. If you have any questions, feel free to email me.

thanks again,
dave

Not sure why hung up on the dash harness question. Pretty much resolved the issue initially posted but was discussing the question with another salvage yard scavenger yesterday who indicated he believed the 66 dash harness did not have the fuse box, whereas the 65 does. Said he had a 66 c.c at one time and the fuse box plugged into the main dash harness. Anyhow, not certain how reliable, but in either case, will make the 1 or 2 connections and the instrument panel is installed.
