Engine Swap EFI 2.3L for carberated 5.7L

Richy23 · October 1st, 2007, 04:22 AM

I have a 1988 mustang LX, and I am doing an engine swap with a carberated 351W from a 2.3> I was wondering how I find the correct wires from the harness on the firewall to power my new engine? Any help would be great, Thanks!

theres already a post regarding the 4cyl to 8cyl conversion.
might wanna check that out and ask questions there.
the author of that topic did a similar conversion and will
have the answers for you.
BUT id think that youd just have tofind a Mustang with a
similar engine(the older carb V8 possibly?)

i used to want to do the same thing

the 351 is a 5.8

and you dont need a wiring harness if your going carb

-cold-machine- · October 1st, 2007, 05:31 PM

you'll need some wiring to hook up the starter and what not
.. no starter no go unless your gonna try cranking it over by
hand like in the old days

Thanks guys. Yeah I'm just trying to find the power to the ignition lock pretty much. I did a similar swap on an s10 4.3 to a 350 but my buddy and his dad went through all the wires to find the power they were looking for and it was just a single purple wire. It was a time consuming task, Im kinda lookin for an easy way out. Thanks

could always go get a manual that has the wiring diagram.
I know Turbo finds the Hanes Manuals useless but
the wiring diagrames helped me alot.
