A friend needs help with an O/T project car

A friend of mine in the Santa Cruz, Ca. area has a project Mustang that has him stalled at the re-wire stage.
The original harness has been hacked into in some places and is in questionable shape altogether.
He has a Classic Inst. cluster and a Painless harness and they are presenting him with many "should I do this" questions.
He has done a huge amount of work so far but he wants to get the wiring squared away before he goes any further.
He has talked to a couple of electrical shops and they gave him some rough estimates. A couple of guys said they'd come and take a look at the project but so far they are "no-shows".
What I think he really wants is someone reliable to work with him so he understands whats been/being done so when it's*****oned up he'll be sure it's done right.

 

What year of mustang is it? is he needing diagrams, cause I have quite allot. and what drive train is in it, I do allot of late model injected swaps. let me know if I can help.

 

It's a '67. It's not injected, right now it has a big aftermarket 4 barrel that may be swapped for one a bit smaller when he gets the car more sorted out.
Wiring diagrams may be a help.

 

we have some alliance members that can build a spec harness.

 

If the problem is the harness to the Classic gauge panel there is probably a wiring harness that adapts the panel to the Painless or oem style harness. I'd be calling the Painless tech line and or the Classic Gauge tech line and asking for suggestions.

There should be a fairly simple solution other than cutting the new harness and adapting it to the Gauge panel.
