Next stop for me is looking for a new harness for my 68 Chevelle. I've check out this from Painless http://www.painlessperformance.com/webcat/20128
I'm putting an LS3 and 4L75E tranny, plus every other option I can think of. Is there a better option?
Thanks for your advice

Zombie666,
The '68 Chevelle harness you posted is pretty well plug-and-play for a fairly stock car, but can definitely be adapted for the LS setup and such. I'm personally running our Direct Fit like that in my '71 Z28 with an LS, Dakota Digital, Vintage Air, etc. and was able to adapt everything. However, I removed a lot of connectors that are pre-terminated, and could have saved money going with the Pro-Series and fitting it to my car without removing stuff.
If you are doing aftermarket gauges, smoothing the firewall, running LED lights, etc. I'd look into the new Pro-Series: http://www.painlessperformance.com/proseries/
Basically it has all the connectors and terminals, but we give you a ton of length in the wiring to custom route and build it to fit your exact car. If you are going to keep the bulkhead connector in the firewall behind the brake booster, the GM Bulkhead option of the Pro-Series will bolt right into the factory location as well.

Can't speak of the new Painless harness, I know Ridetech used one of their new harnesses on the latest 48 hour camaro build. There are many on here that are fans of the American Autowire Classic Update harness. Great piece with an excellent tech department.

Some awesome sponsors on the right side of the board that can help you get it at less than retail. I like using Matts Classic Bowties! Matt, Kim and crew are great! https://www.mattsclassicbowties.com/

I also used an American Autowire classic update with similar mods to what you have planned. Very pleased with the outcome
