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.

have you tested it?
if so....its about time someone did this and shared the proper way to do it

 

yeah works fine.

 

Good ****!

 

Ah the complex process of wire matching and soldering .

I"m just busting your chops, nice writeup, maybe this'll down the number of newbs asking "how to."

!!

The H-T community thanks u on that one .

 

do u have a diagram for 00ex dis harness to 00 si dis

 

Nice job man. great looking finished product

 

Nice write-up.

 

Where did you get those plugs? Was it a dist. that you had laying around? Because if so then i would have suggested gutting and swapping internals. Super easy.

Good write up none the less.

 

should be a sticky.....GREAT WRITE UP!!

 

rep

 

just holding my place for future referance.

 

Nice write up. Wish I saw this when I first did my swap

 

yup thats what i have to do with my swap this week actualy...good timing..lol

 

Looks good!

 

great DIY but for those who do not want to chop up the harness, PasswordJDM has a conversion harness for $25.

 

unless you can't wait for shipping.
Saving this for later.

 

next time just pull the pins and re pin it.

 

just holding my place for future referance.

 

looks good. I had to do this 2 years ago. for taking the time to do a write up for others.

Good write up
