Which TBI harness to use

[Fatrat]

Alright, finally made the decision to go with fuel injection and yeah this is my first time, but have been lots of reading. I have the complete engine from a 94 suburban along with a 4L60e tranny and PCM #16197427. This set up is going in my wifes 1972 C10 that i'm building. I do have the complete harness, but have never reworked a factory harness. My plan is to buy a pre-made harness and use it as a guide to rework the factory one which i will later use in my K5.

The question is, of those of you that used pre-made harness, what is a good one to get? I heard painless is not painless at all. I tried contacting the people at fuel injection connection all day with no luck. I also tried calling affordable fuel injection and howell's but it got too late.

Any input on this, i would love to learn to rework the harness myself but don't like to be spoon fed. i tried different searches but couldn't really follow along so i'm taking this route. Help me learn.

I just bought an Affordable EFI setup. Everything is labeled clearly and it looks like a good setup. I can't remember the guy I spoke with but he was very helpful. They were 1-2 weeks on making kits and everything shipped when he said it would.
Hopefully it installs just as easy. Should be a 4 wire connection and done

I've heard good things about affordable. The fuel injection connection harness it's almost 100 bucks cheaper but i'm looking for something of good quality and ease of installation.
My uncle used affordable and love that it's only like 4 wires to hook up. So, with big pappa, this makes two for affordable.

And not to get off subject, but this is the 72 that is getting the new TBI 350.

I used Howell on mine and zero complaints, even a wiring idiot like me wasn't too confused.

I’ve used Howell harnesses on a couple EFI swapperoo projects as well as used them for ECM/Prom tuning. Recently had an issue getting a 4.3L to 7.4L project tuned properly the first 2 tries but they made it right at the end of the day. I highly recommend Howell. My least favorite is Painless. Painless doesn’t even cover their harnesses with split loom for crying out loud!

Try the link below modifying a stock harness is not to hard, just takes time.

Well i tried calling several places and sent emails and the only ones that have answered is howell so even thought they are a little higher or price, i might just go with them. Seems like their customer service is much better.

Thanks for the link 85Kdsl, it helped as i started reworking the other harness. Unfortunately the person who took off the harness just broke off the connectors at the sensors, so i'm having to replace those.

Thanks for the input

Next thing will be burning my own chips.
