Title: Ignition Wires for COP Kit
Post by: vpilarry on February 11, 2013, 08:44:03 PM: NMNA - http://www.r3vlimited.com/board/showthread.php?t=278534 (http://www.r3vlimited.com/board/showthread.php?t=278534), see the "m52b28 coil harness".

You can use the 4 longest coil harnesses out of this and hide the splices to the OEM harnesses under an M3 firewall cover (if you have one). Here's a pic of mine:

I'll need the wiring diagram and part numbers to install this on my car.:D

1) Before you remove the harnesses from the coil pack mark each one so you know which one goes to coil #1, etc.
2) Remove the 4 longest sets from the M52 harness.
3) Install the COP Kit.
4) Install the M52 wires onto your 4 COP coils with the longest at coil #1, etc. Dress them as you please - I used heatshrink tubing.
5) I crimped 1/4" terminals onto the M52 wires (I forget if they're male or female - it'll be obvious).
6) Plug the coil #1 M52 wire into the cars coil #1 wire connector - match the wire colors at each connector (black to black, etc). Repeat for the other coils.
7) Instead of steps 5 and 6 you could just use wire splices but my method allows you easily convert back to the original setup if you ever want/need to.
8) Hide the connections behind the M3 panel. I cut a piece out of the bottom of the panel for the harness to feed through - see my pic above.

Thanks, Rob!
