FB Getting a swap. Need help!
 

So plans were originally to build another 12a motor, I have quite a few laying around the shop that I can pick and choose parts from and whatnot.

But recently, my boyfriend picked up an '87 FC GXL.

His plan is to swap his ka24DE into the FC shell, since the guys that had it before us have already ripped out most of the things that actually make this car an FC, other than the engine. This leaves me with a spare 13B fuel injected motor that we now want to throw into my '85 GSL.

Tackling the engine has proven difficult, because my FB is carbed, and all of a sudden I have this huge wiring harness and an ECU to worry about. The FC is a fuel injected 13B, and the guys before us have already pulled all of the interior wiring harness apart, meaning I don't know where everything goes. The last engine I pulled, all I needed was the engine, so I just chopped all of the lines off of the motor at Pick and Pull (for practice, I had never pulled a motor before then)

So this leaves me with a few things that I want to find out if they are options....How can I get my hands on a new S4 Wiring harness? Is there a way to easily adapt that wiring harness to my FB? What pieces of the wiring harness am I not going to need (ie. Lights, steering column, windshield wipers...)

Another thing I was wondering about....
Can I try to track down a wiring harness from a GSL-SE, since that would be the 13B motor as well? Or would that not work because this motor is pulled from an FC?

For example, would this work, or does it mess it up because it's an S4 engine?

get a Used harness off the Sec gen For Sale section...if you are putting an Series 4 engine in it.
No sense in hacking up a brand new harness.Seriously $500 bucks for wire is a little insane in my opinion!..unless you are "really Picky"!
I'm not sure about the GSL-SE aspect of it,since I am a FC guy.
OH..the CDN section FS Section may be able to hep you too...seeing it may save you shipping if you need parts.
If you know Rx7 Guys in BC,they may know my name.
