Question about 3G alternator install using FFI harness

[Mike92GT]

Who's installed their 3G using the Ford Fuel Injection wiring kit? I'm wondering if using this will allow me eliminate the factory wiring, mainly the two 10 guage black/orange wires. I've read that these two wires have to be kept because they splice in to something else down the line at the starter relay. I'm trying to make room on my relay for other stuff. Thanks

As you see, the two black/orange wires join to become 1
dark green wire, which is a fuse link. Removing it won't
make much more room on the starter solenoid post. I
recommend that you visit an auto stereo shop and find a
suitable power distribution block for the additional
accessories.

Here's the 3G shopping list for wiring parts to make your
own harness & save some $$$


See WWW.partsexpress.com for the fuse & fuse holder.
Fuse @ $3.90 each (need one) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=071-952

Fuseholder @ $5.80 each (need one) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=263-630

4 gauge black wire @ $1.25 a foot (use string to lay out routing & determine length) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=100-196

4 gauge red wire @ $1.25 a foot (use string to lay out routing & determine length) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=100-194

4 gauge ring crimp terminals (package of 5) $3.25.

3/4 “ Black heat shrink tubing, 4ft length, $3.39

Pre-fab 4 gauge cables with lugs already on the ends are
available in most auto parts stores. Look for the starter
switch to starter cables.

I used the section of the stock 3G harness (same as the FFI unit.) You'll find that the only real need for that harness is for the small stator wire connector. The oval (or D shaped) plug from the 2G, plugs right back into the 3G alternator. I clipped off the power wire connector and saved it for later.

JRichkers power distribution block is the best way to get rid of some stuff on your solenoid post.

Thanks guys. I'll look into the power distribution block
