On my 2002 GT there is a 42-pin connector under the hood.

Pin #9 appears to be the single 12V source for the injectors and about 4 other sensors, that divides into about 10 different 12v wires which creates a huge mess of wires making the Megasquirt bundle of wires extra large and messy.

In an effort of minimizing wires I am wanting to create a single 12V contact point that I can cleanly/safely connect the injectors and other sensors too.

How are others cleanly getting 12V to the inj's and sensors?
Any suggestions on doing this?

I use a bus bar. 12v into the bar, and I can stick up to 16 connections to it via screws on the bar. Can't say its NOT still messy, but thats more because I've not done wire management yet than the bus bar's fault

 

I'm looking at bus bars now. If anyone has a specific one they like that is covered/insulated can you post a pick or link to it.

I used this one (but in red, can't seem to find that one now)

Its nothing complex but works well.

 

Rus EFI might have a breakout board for your connector if you haven't cut the connector off yet.

 

I found a few bus bars from McMaster that I'm gonna try and to help clean up the wiring it looks like I need one for the coils and a separate one for the injectors:

In addition, I have a few wires that I need to replace and I prefer to use the same color scheme but having a difficult time finding the color that I want. If anyone has a good source for the below let me know. I've tried Digikey, Mouser, Newark, McMaster. I need 20ft:

20ga, Grey/Red..

No need for new wire I got the wiring figured out.
