I found these pics and remembered that I "owed" them to you. Hence reviving this dead thread. The light really wakes you up at the track - something a tach by itself would never do. It is amazing what an amount of photons come out of this small thing. It must draw an amp! :D

Here the light installed:

Here how you have to hook it up. This is "testing" it, just squeezing the wires into the stock connectors. Take it as a poor mans wiring diagram. Later I spliced the wires in there with 3M splice connectors. You see, it runs right off the stock juices. Those 3 connections is all you need.

Here the trigger control unit, with a 3.0 krpm test bean installed. That bean comes on at a convenient 3000rpm so you can test the unit. Then I installed the real deal 6000 rpm bean, which is perfect to wake me up and give me some time to upshift or stay on it before I hit the brakes. You can buy bean sets with any rpm in 100 rpm steps.

And here the shift light in action at Laguna. You won't believe it, but likely you'd see the yellow of the shift light, before you see that yellow monster in your rearview mirrors. :D

I hope this helps others install this gizmo. It defintely gives me piece of mind, especially since I am a novice to track driving...

Cheers, George

Thanks for the pics, I'm sure I would have been confused about which wire goes where. One more question - you tested from the spade connector but there are actually several factory wires that are connected to the factory spade. When you spliced into the wires, which wire did you choose for each spade? Or did you simply buy a piggy back adaptor for the spade connector?

If there are two wires connected to one spade connector then any of the wires will work. Imagine it this way. If the spade connector was a foot long copper bar instead you could touch the copper bar at any point and that would complete the circuit.

Great pics George! Thank's! I will get one in the car before Willow this September.

This is the type connector I use. Note that it does not ruin the insulation of the wire you splice into and it does not cut the wire you splice into.

I did not want to piggy back on, because two of the factory connections to the tach are already double / piggy backed.

As masraum mentioned, it doesn't matter which wire you tap into, if they go to the same terminal.

I bought a slightly different rev light and am not sure how its wires correspond with the picture above. It has three wires - power, ground, and tach signal. How would these wires correspond with the color coded wires above?

power = red
ground = black
tach sig. = green

I am slightly color blind. In the pic it is starting, closest to the camera and going away from it:
ground - tach signal - power

Hope this helps. Just look it up in your manual if in doubt. The shift light also should come with instructions.

George

Thanks again George

George

I think I'm finaly going to do it this weekend.

Any update bigrubberjeep?
