explorer swap what wiring harness

[papy]

Hi all,

recently saw a post but i cant seem to find it. so here it is another wiring question...

77 bronco with explorer 5.0 /4r70 EFI guy reworked engine/transmission harness. wondering what aftermarket harness should i be purchasing for the remainder of the build. other than the explorer swap its pretty much stock

thanks

What is your level of experience wiring? Do you have the ignition wired and working?

i am somewhat familiar with the explorer swap but it been about 5 yrs since the last one i did. not a whole lot when it comes to wiring however i do have someone with experience that i can help with the install if need be. id rather not call on anyone so i would like to keep things as easy as possible on my end.

no i have not wired anything up on the swap yet. juts getting ready to pull the motor this week.

I used to like the centech harness, however they are no longer being produced. I would look at the new one from Northeast bronco/ Del Conick.

I just did a generic American autowire and it was easy

You can use a Ron Francis engine harness that will wire into most Bronco body wiring kits.

While I haven't used this harness yet, from what I am seeing/reading it is very similar to the old Centech harness, which was simple to install and relatively complete. Not a lot of options for accessories though, like the AAW harness.

With Gary's harness and how it is configured, you have about 10 wires that need hooked up. Power to the fuel pump being the simplest. You will have to tie into the chassis harness when you configure the back-up lights power/return to the lights themselves and the neutral safety switch. You will need some 12v power in start/run for the overdrive cancel switch and check engine light.
I used some weather pack connectors so I can separate the two harnesses if ever that was needed. Having just done Clifford, it still is sorta still fresh in my mind...

thank you. i will look into the northeast harness.

so once Garry EFI guy reworks the firewall, engine and transmission harness i only have about 10 wires to hook up total? does that include the head lights, turn signals and behind the dash stuff as well?

Nick's harness seems complete, like the Centech was... Most of the Centech harness was finished and you just routed the wires to the related components and plugged it into the factory plugs, switches, etc.

The EFI harness will require that you tie those (approximately 10 wires) into whatever main harness you choose to purchase...

I have used the Centech harness in the past and I have used AAW products for the last few years. The AAW gives you more flexibility to add circuits for other things.
