P-n-P Extension Jumper Harness.

[SuperNova]

Has anyone ever heard of, or used these from RHDJapan? I just came across them today and was kinda curious about them. Seems like a good alternative to extending it yourself and drilling another hole in the firewall. It would also be good for adding in things such as a piggyback, and you won't have to cut into the original harness.

Not a bad price at all. IIRC, the NSX one works as well.

The issue with this method of 'extending' your harness is that you'll end up with a giant connector right over the exhaust side of your engine in the engine bay. Also, this does not extend the body plugs, only the ECU so you will still have to do the wiring on those. You'd also have to separate the connectors somehow (maybe with a dremel) to even get the plug to fit through the hole in the firewall.

If you're thinking about getting a jumper harness though, http://autosportwiring.com/ is another option, also there are alot of cars with the same ECU plugs as the 1jz out there if you want to cut the price and make one yourself.

I think Dr. Tweak on here makes them, I don't know how much he charges though.

You dont need to extend the harness.
You can keep the oem harness install it better & safer save down time & money.
There is many write ups on how to do the safely.

Oh, I don't plan on getting it, I just thought I would share my findings. lol. Thought it might help if someone was looking for something like this. I've already decided to drill a new hole. And JonoTurbo made a good point about having a clump of connectors to make it look cluttered.

Not sure if this site is old news to most people, but they have a lot of other stuff on that site too that I haven't seen anywhere else.
