Super Clean Line Lock Switch Installation

by: Michael J. Christopher (MJChristopher)

I figured a line lock would come in handy at the track, and as luck would have it Santa (a.k.a - Dad) bought me an SLP Line Lock for Christmas. So, the question became....Where to install the switch? My key criteria were: Easy to reach, very low key, and no drilling holes in the dash/console. I was very happy with the results, so I thought I would share. I prepped the switch install location and Stevie from MM (big thanks!) installed the line lock hardware and routed/connected the wiring to the switch.

Summary: I found a switch that was the perfect diameter to fit into the hole for the electrical plug next to the shifter. Some very easy modifications to the electrical plug unit permitted the switch to be installed and the wires routed out the back.

Details:
Switch Used: Round rocker switch w/ Green LED. The key is that it's got a 16amp rating (similar to what is supplied with the SLP kit) and a pressure fit body meant to be pushed into a dash plate. The one I bought is from Oznium, who also supplies switches used by Speed of Sound. This is the link to the switch used, any similar style and size switch should fit: (http://www.oznium.com/rocker-switch)

Steps:
1) Unscrew the shifter knob and pop the center console trim piece out, unplug the electrical connection.
2) Remove the electrical plug housing from the console trim (pops out).
3) Using a small drill bit, drill directly into the small rivet found inside the back of the electrical plug housing. (See pic below). Once you drill through the rivet, the back piece comes right off and exposes a hole for routing the wires through.
4) Insert the switch and pull the wires out through the hole in the back of the electrical plug housing.
5) Push the switch/electrical housing back into the console trim piece.
6) Review wiring notes (included below) for lighted vs. non-lighted switches.

Note: A generic wiring harness or insulated spade connectors should be connected to the leads from the switch when performing the wiring to ensure that you can still disconnect the switch wiring to remove the shifter console trim piece after install is complete.

An MSD generic three wire harness was used to ensure that the wires could still be disconnected to take the console out. Insulated quick connect spade connectors would also have worked fine.

Wiring Notes: The line lock comes with pre-made wires intended for the switch to be on the ground side. This won't work for a lighted switch, because the lighted switch needs to be on the hot side. Below is a sample diagram of how the wiring is modified to accomplish this.
