Testing a 4G63 wiring harness last night.

[4g63mightymax]

Last night it was too cold outside to test a cleaned up 4G63 wiring harness. So..... I tried it in my living room. I am going to do injectors next.

I figured some of you would enjoy it.

Well, nobody commented on it, so I will assume you enjoyed the last video.

Today I have another wiring related video showing how I remove wires from the ECU connectors with hair clips. It works perfectly, and keep things clean & neat when I am cleaning up 4G63 harnesses.

Enjoy.

That second video was pretty slick.

That second video was pretty slick.

Thanks! That is how I've always done it, but it dawned on me yesterday that it is really frickin hard to do if you have never done it before! Thus, I Youtube'ed it for the masses.

To be honest, I figured the first video would be more impressive. Ah well. I need to try harder next time.

Very nice!

I think its more of which one would be usefull to most people. I know lots of people who need to replace or repair a harness connector. However not near as many who need to test a complete harness before they install it.

You make an excellent point! Are there any other DSM wiring related topics that people could benefit from?

I've often wondered what it would take to make a factory harness into a standalone style for a possible 4g63 transplant; such as which pin #'s can be removed and other needed modifications. If you'd like to shed some light on the subject I'm all ears and would greatly appreciate it.

I like your Pin Removal Tool.

I've been using a thick sewing needle, your way looks a lot easier.

if you look at the wiring diagrams for just about all Mitsubishi's (1G's, 2G's and EVO's i know for a fact) basically if you pull the harness out of the car and use it in conjunction with an ecu that plugs into it you are good to go..... for a 2G car there are only a couple of connectors that are incorporated into the harness that don't do anything with controlling the engine. reverse lights and speed sensor the big one near the coolant catch that sends power to the ecu and relays and that little black box near the BCS that has something to do with the voltage regulator (or so i have been told). everything else you pretty much need for the engine and emissions control.if you really wanted to you could just take the wiring harness and use it as is. all you would have to do is wire in power.... may be add in fan controll, power steering switch, and low oil????

This is true. A 1G harness cleaned up is basically a nice standalone setup. You hook up ~3 wires to power, and 2 grounds, and have yourself a running engine, with a working MPI relay and all.

I haven't played with 2G harnesses before because it seems like nobody wants them. If there is a use for them, I will grab one and customize it for the learning experience. Got any uses for them?

same use as a 1G harness for a PNP 4g63T swap. could be used with 98/99 flash ECU and EVO8 ECU..... flash upgradable... and it can pass OBD2 emissions tests (good for newer cars)

Could you take a pic of the big connector that goes to the ecu on both the top and bottom side. That would help me out so much with my wiring situation.

If you tell me why? Did you pull all the wires out at once?

I would like to know if it is possible to buy brand new exact replacement connectors from somewhere. Right now the one I would like to have new is the connector that plugs into the 1990 power transistor. A while back I replaced all the connectors to the ecu but it cost me $100. I bought a Field CN-15 harness from Perfect Run in Australia and cut it up. I would have just bought the 3 connectors if I could have.

Plugs, Pins, and Connectors - EvoEcu <- 1G - Evo9 Ecu Plugs

If you know the brand and style of connector you can get it from somewhere like Mouser Electronics - Electronic Component Distributor

MITSUBISHI CABLE AMERICA, INC. is good for part numbers.

Sure enough another video. This time with more flashing stuff in the dark.
