Anyways, here's the picture;
List of parts I used;- 10 ft of 16 gauge Red wire
- 4 ft of 16 gauge Brown wire
- 4 ft of 3/8" single wall shrink tube
- 1x fuse box pin (BMW p/n 61-13-8-377-732, or VW p/n N-907-327-03)
- 1x M8 brass ring terminal for 16-18 gauge wire
- 1x Sumitomo 250.ARM-2S-1 connector and pins
- 1x eBay find E92 BWM power socket assembly consisting of;
- 1x Socket mount BMW p/n 51-47-6-964-057
- 1x Socket holder BMW p/n 61-34-6-843-098
- 1x Power socket BMW p/n 61-34-6-973-037
Power lead ( red wire) goes from pin 162 of the rear fuse box to the center pin of the power socket. You have to remove the blue connector from the backside of the fuse box to be able to slide the BMW/VW pin into the appropriate spot.
Ground lead ( brown wire) goes from the chassis ground almost immediately above the amplifier to the outer pin of the power socket. Hence why it's so much shorter than the power wire.
Un-heated 3/8" shrink tube was used to cover both leads between the power socket and the chassis ground providing abrasion resistance. After that, I secured the power lead using small zap straps to the existing harness. I left plenty of slack on the shrink tube section to make it easy to connect the wire harness to the power socket when the trunk liner wasn't fully installed.
Wire harness essentially chases the amplifier wiring to the trunk bulkhead, then continues down to the floor of the truck using the existing harnesses as a guide.
Hole in the trunk liner was cut using a new/sharp #11 Excel blade using a template I created. I'll try to add that to the bottom of the post in case someone else needs it.
Next I'm going to add the under dash and rear console power sockets... wish me luck haha. |
Nice! Not something I would go through the effort to do myself, but I'm sure that this will be helpful for someone else who wants to do it too
