914World.com _ 914World Garage _ 911 to 914/6 engine harness

Posted by: echocanyons Jun 3 2005, 08:05 PM

I have a 81 3/.0 six cyl engine and I want to use it in my 74 914.

What all does the stock main engine wiring harness connect to?

What are the basic things I need the harness to connect to?

Alternator
Starter
VR
Coil/Ignition

Since no one else has replied, I'll give it a try.

Use a internally regulated alternator and the wires go right into the stock relay board.

The starter and coil/ignition are the same.
You'll *want* to wire it all nice and tidy through a Pertronix and MSD 6AL box, though...

If you are running carbs, you can take "key on" power off the no longer used terminal from the F.I. harness, also on the relay board.

Using F.I.-

Thanks Trekkor
Well I am still debating on going the 3.2 DME(I have a setup minus the DME) route or PMOs

The biggest problem I have with the harness I have is I dont have one so I was thinking on ways to fab one up or pick up a used one.
I was just wondering what components I would need incorporated in the harness.

You can lose the relay board.....you will need a wiring diagram for the DME set up if you use the FI, I have it one one of my hard drives someplace.

.....if you don't have the stock harness for the six....it's best to find one or buy a "Painless Harness"...I'm using that on Frankenstealth my 2.2/6 powered 356...

If I get another motor someday...

I would love to have a set of PMO's.

After I got my carbs cleaned up and adjusted, I have been having nothing but a blast with this car.

If I ever get a set of PMOs....they will be buried with me....

I see them often on ebay (engine wiring harnesses). There is a 3.0 engine harness on ebay right now that ends in 3 hours...it's at 25 bucks. Here is the url:
