Has anyone here used a centech harness for the vehicle or for a
fuel injection motor ? Just wanting the particulars of if ,and , how
and why .:flipoff2:

I have a centech wiring harness to replace the wiring in my EB. I havent put it in yet though. I hope that helps you alot. :flipoff2:
Everything ive heard though is that its simple and straight forward, ive gone through the instructions and they are complete. Same with the Wiring harness, ist made very well.

Thanks alot Stoop , I appreciate it ! :flipoff2:

I have a centech harness in my rig. It's not injected but I hear they make custom add-on harnesses so you can run an injected motor. The installation was simple and straight forward, and they even tell you what to do if you have a glass body( which I do), aftermarket gauges, aftermarket ignition, or a non-ford charging system. They take out alot of guess work.

Great info on this product , I've heard others speak highly of Centech and their customer support . Ya'll cleared up some ? 's I
had if it would work w/ aftermarket charging products , gauges ,etc . Thanks again :flipoff2:

Fawk the centech harness!!! I have one and it was the biggest PITA to install. Wires were too long and needed cleaning up like no other. Ignition wiring diagrams were nowhere near detailed enough, and I had to search for other resources. Definetly not set up to accomadate aftermarket gauges very well. My conclussion is that is you aren't running a stock EB you should buy a few spools of wire, some loom, and a fuseblock from that francis racing character. That would certainly be the way I would do it if i had to do it again. 400 bucks for a wiring harness... whatever.

Dragging this one out from the dead since I picked up a 74 Bronco for my sister and the wiring is a rat's nest under the dash.

Any other suggestions if not Centech? $900 for the Painless one makes my wallet hurt just thinking about it, and I found a $100 kinda universal one on ebay...

BTW - hers is stock as far as wiring needs are concerned.

Wild Horses sells the Painless harness for about $550 and I gotta tell you, it was soooo easy to install! I would buy again in a heartbeat.

I think the guy that said to buy a spool of wire and a fuseblock was on the money. Unless wiring gives you sweats and you will loose sleep at night.

I have parted out a few Regals and saved the fuseblock because it could so easily be used in any vehicle. 1 hot wire powers up several fuses for several circuits. New style blade fuses. An early Bronco does not have that much wiring.

I was thinking more about cleaning up under the dash instead of rewiring the entire vehicle.

Does the $550 kit include the entire wiring, lamps and all?

I have a Centech in my trail rig, which I spliced my EFI harness into. It works great and was easy to install but it has way too much stuff (extra wiring, unneeded circuits) for my trail rig so I've pulled it out and will put it in my wife's EB at some point in the future. I want to re-wire my trail rig myself, using a simple hot-rod fuse block and wiring. If the Bronco is more or less stock, the Centech is a great, easy way to re-wire it. Everything just plugs in (with a few minor exceptions).

Yeah, my sister's is stock (well, as far as electronics are concerned), and I'd really just like to clean up the wiring under there and throughout the vehicle. I will get a picture tonight of under the dash - it's INSANE.

The RJM fuel injection harness plugs right into the Centech from what I understand.

The Centech and the Painless are both pretty straight forward, anyone having problems with them is definitely going to have problem with any harness. They've made it about as simple as it can be.

DRM - be sure to order the adapter for the Centech to use your stock ignition switch.

BC Broncos, Wild Horses and some others all carry the Centech. WH carries the Painless, I'm sure others do too. What sets them apart, is that the Painless comes with all new switches, the Centech uses the stock ones. There's a lot of neat stuff that's a simple add-on with both of them, headlight wiring upgrades, 3G alternator and stuff like that. They've both done a good job of making it as user-friendly as possible.

I haven't talked to anyone that's used the Painless EFI harness, so I don't have any feedback there.

I was wondering about the one on ebay as well, Looks good but what can you tell from a pic

We've gutted my friend's YJ, and I think he might order one just to get the basics covered since that one looks like more of a universal kit.

I'll post up the results if we install it.

I bought my centech harness about 6-7 years ago when it was around $400.
I run it combined with an 87-93 mustang harness on my SEFI 351W. Wired it, fired it up, never touched the wiring since, nothing has ever failed on either the centech or the mustang harness.

It's veeeeerrry generic.

You can get a harness like that just about anywhere. There's a place here in Dallas that sells a similar setup. For a buggy, or a trail only machine, it'd be fine, for a street driven rig, that's going to have stock lighting, gauges and everything else, I'd go ahead and pony up for a Centech or Painless. Save yourself a lot of headache.

Here's the place in town that has similar harnesses for sale:

Thanks for the info

I just installed a centec harness a few months ago. i thought it was pretty easy. I run the mustang harness for the EFI. THey went together pretty easily.

The painless harness is the bomb. Even a drunk monkey could hook it up (which is lucky for me). The new switches as mentioned are a huge plus, imo, when dealing with a 30+ year old electrical system.

Damn this thread is old. I got my Centech harness installed sometime within the past 4 or so years. But i still dont have the thing running. :D

BTW - hers is stock as far as wiring needs are concerned.
My only thought is, everyone on this thread, and on this board can say that about themselves at one point in time. She gets biten by the bug, and she might appreciate having an upgradeable wire harness. Or if she ever decides to sell, the next person inline might pay extra for it.
