So I purchased a shift light from Summit Racing. A proform shift light with built in rpm adjustment.

I hooked it up to the coil as the how-to shows for the raptor light.

However, on install the light blinks constantly and I can set it.


So I have a few questions:

1. Should I tap right into the orange/white wire from the PCM?

or

2. Purchase a tach adaptor for the light itself?

Please dont just reply with , but a Raptor as I am not a fan of the style

Thanks guys for any help.
