First you need plugs and tools



Now strip all the wires on the plugs/connectors


I usually make a hook on both sides on the wires to hold them together and solder.



Then shrink wrap the wire. You can use a lighter if you don't have a heatgun


Once everything is shrinkwrapped, you should have something that looks like this.


Now wrap the wires with the wire loom, and use some black tape on the ends to hold it together. don't do a sloppy job.

MAD PROPS! I'm do dis too

Good stuff

Is this for a OBD2 Distributor connected to a OBD1 Wiring harness?

dem0nk1d

yes this plugs into a obd1 harness so you can just plug in a obd2 distributor with out having to change the plugs everytime.

Pssst!

Would this work for making a obd1 dist. into a obd2 harness or does the obd2 have extra sensors it looks for?

nice write up! props

Never thought of this. I have always re-pinned the connectors. This is a little easier and is able to be done without a honda pin kit. Wish you would have done this writeup about 2 years ago.
