I haven't done a dbw harness yet,but subscribing for the great info.

Found this information at lt1swap.com ( http://www.lt1swap.com/wiringharness.htm ). One relay to supply brake inputs to both TAC and PCM.:thumbsup: The wire from the brake switch will need to wired to both (spliced together) with the relay input (termainal 85) and TAC module brake switch input. I've decided to use Hella Relays #75601 relays and Hella connectors #75610. Hella relays are used by the factory. I'm thinking why risk using low cost relays that are not weather proof? Cheap is not good:yikes:...good is not cheap!:thumbsup:

I use nylon split loom to wrap the harness, its the same quality split loom as the original harness was wrapped in. The trunk / branch method I use to wrap the harness uses more split loom than the original harness, but provides for a quicker and cleaner looking install. The person I helped with this harness really appreciated the level of service and parts I provided.:jfj:

Excellent work Dave, but I would expect nothing less from you. Very clean harness. Some day I will build something with a LS engine and when I do I got your #.
I have been busy building a 64 Ford unibody pickup for my Uncle to take to Good Guys in Fort worth. I c-notched the rear frame and installed a Camaro front clip, I got it down in the weeds and it drives and handles great. All old school stuff no EFI.

Looks nice and clean. Nice work!
CJ-7 ehh, or may be a CJ-5, cant really tell from the pics. Power brakes would definately be the nex thing on my list of things to do after that swap. Lots of go, and not much woah....lol
So what is done with the transmission wires on a standalone harness w/ a manual trans. or a non OD trans.?
Removed from harness? Or, just cut taped up?
Any trans. wires needed to tell the pcm it's a non OD or manual trans.?
What VSS did you use? Is there a cheap speedo cable driven VSS that works in Jeeps? like the TBI 2PRS from jagsthatrun?
I removed the wiring from the harness completely,if needed at a later time it can always be added.
keep it in there if you know you'll be switching it up though.
The programming determines the trans type.
Below is thread about using the low cost Dakota Digital VSS. http://www.dakotadigital.com/index.c...620/prd620.htmQuote:

There is the option of programming the PCM so the VSS is not needed. I recommend using a VSS for any vehicle that will be driven on the street.
