i have been looking on ebay for the conversion harnesses and some have extra wires hooked to them and some dont. wasnt sure if both work fine on if i needed the one with extra wires.

 

www.rywire.com is your best bet for the ecu jumper harness. Im assuming thats what you're talking about.

 

For a cheaper price than rywire...monotech. Search that on honda tech it should come up

 

ya i have a 88 crx with a b16 swap in it runs good just turboed it and want to put a p28 ecu with hondata s300 in it to tune it. was just woundering about the different conversion harnesses. one has sone wires off of it and some dont was woundering what those wires are for and what they hook up to.or if i can get the jumper harness that dosent have the extra wires

 

I used a Boomslang OBD0 to OBD1 Conversion Harness. Had all the wires already spliced at the ECU jumper. All I had to do was follow very clear and easy instructions to wire the underhood stuff. I had no problems.
