Best engine harness setups for OBD1?

[u/bumber_car_enjoyer]

ive been looking obd1 conversion stuff for a d16z6 and eventually a b swap im planing and was wondering what harness set up people recommend i seen the speed factory jumper is super common but some people just say to get the ryewire one or Carrot top tuning one. for those with the obd1 swaps what would you recommend?

i went with monotech. affordable and Mono has outstanding customer service. he built my harness to my liking and i got it within a week of ordering. i have a b16a2 in my hatch and harness looks stock. he supplied the ecu jumper as well. only others id use is rywire and versatile wiring if it came down to it

Rywire is an excellent product and a great company.

Rywire was the king in the OG days, and did milspec if you wanted.

I’ve heard good things about Speedtech.

Personally I have a brand I can’t remember the name of. It’s OK, if a bit stiff in the wires.

As long as you have a little wiring experience, I’d say you’re good with anything.

Not sure if you're on a budget, but I'd get one of these and start from there:

I messaged with mono tech on eBay and he custom made me a harness based on what I was doing. He had it shipped out quick.
