I just bought a 89 crown vic that I was going to take the 302 motor out and put it in my fc. I was wondering if I would be able to use the wiring harness from the crown Vic on my rx7, and was also wondering if a 5 speed tranny from a mustang would work with the 302, I'm on a budget

 

the t-5 tranny from a mustang should mate up to the motor and the harness will work but will need to be wired up to plug into the rx7. my swap was done carburated and i have been planning on converting to fuel injection for possible boost later. but if you come across an easy way for the harness let me know

 

Ohkay cool thanks I was thinking the Td would hook up to it. Did you have any issues doing the swap? This is my first motor swap I'm doing on my own

 

Take a look at Grannys speed shop web site, search around and you will find the section for 1st gen RX-7 swaps, then find the Ford 302, and finally a section for Brad Bergholdt's conversion , with details of the wiring and other parts. An excellent writeup, I think the guy is an auto shop teacher.

Keep us updated on the harness mate! I'm trying to budget for a standalone TBI but if you can figure out how to work the factory harness that would make life a little easier

 

im in the middle of this swap myself. i have a 94 mustang gt motor going into my s4 vert. i have my buddy doing the wiring for me. its next on the list. giving him both my harness and letting him work his magic. ill update you as i go.

 

another thing is the t5 has a transmission tag on it if you don't know what it came from. make sure your clutch, flywheel, clutch fork, and bell housing all come from the same make/model. input shaft sizing changes making the changes to these parts.
