Wiring harness advice

[Mkelcy]

So long as you're staying pretty much stock, I agree. The M&H stuff is perfect and ready to install immediately with no fuss. Once you start straying from stock configurations, not so much.

I've used their stock replacement stuff and it is, as you say, perfect. They also seem to offer an "update" harness, but I haven't seen it or used it. It might be worth a call to M&H to see how complete it is if you're not fond of crimpers, etc.

IMHO the update harness is only good if you can provide absolutely perfect descriptions of your changes - including wire lengths. Otherwise.... Truth is, if you're staying pretty well stock you're fine. If you're deviating, no matter who you use it's gonna involve some thinking, documenting, cutting, routing, crimping, soldering.....

AAW all the way..... stay away from painfull

Agreed.
I just put an AAW Hwy 22 kit I bought from Musclerodz in my 78 pro-touring Camaro.

Zero wiring experience besides numerous car stereo installs.
I can honestly say it was a piece of cake because of how simple they make it.
I know a HELL of alot more about wiring now because of it. Mine is completely custom with a LS1 in it as well.

I bought a weatherpack crimper tool off Amazon for $27 and a Weatherpack
connector kit off Summit for my aftermarket gauges to complement it. Then you
just need some wire straps , heat shrink kit, good crimper tool, a GOOD soldering gun, and GAME ON!!!!

I bought the Painless kit a while ago (before AAW was around or well known anyway) and it went in ok except for some minor issues. I called tech support to get a schematic and they would not give me one. They said it was proprietary??? They said just call me from the car and we will troubleshoot it together. I said"I don't work on the car when tech support is open". Sorry.....Last time for Painless. I would look elsewhere.
Good Luck

I will never use a painless product again. I bought the 18 circuit kit for my '68 Camaro and the upgrades to an RS with a high output alternator, and an original ammeter have dang near stalled my project. The wire lengths in the loom were nowhere near what would actually fit the car. Painless' tech support did not even know that the RS was any different than a coupe. Other than shipping me a very small supply of terminals so that I could reuse an old connector shell they were almost useless.

I used a Painless harness once. That was enough.

so what would a kit cost to re-wire a whole F-body?
