Shift light

[1/4 Mile Junkie]

Hi guys, how's it going? First off I would like to say that you guys have a wonderful site. Keep up the good work. Here goes my question. Does anyone have a shift light from Harlan? I bought one hooked it up and it only works at half the rpm eg. I set it for 5000 rpm it goes off at 2500rpm 7000 it goes at 3500 you get the picture. I have an 03 Silver and Grey. Maybe I tapped into the wrong tach wire. I have the cylinders set at coil per plug. Any help would be greatly appreciated

You need to set it up for 2 cylinders so it will come on at the correct RPM.

Thank- you very much Blue Streak. I'll give it a try

I just set it up and it works perfect. Thanks again Blue streak. How come you don't set it for coil per plug or ar least 4 cyl? I know it has something to do with the electrical pulses from the tach wire

No problem glad I could help.

I have no idea why you have to set it up for 2 cylinders. My guess would be the tach signal wire only recieves signals from 2 of the coils.

Makes sense to me but then I'm no electronics expert as you can tell. Thanks again. Can't wait to try it out this weekend with the nos. I got it so I wouldn't have to have my eyes glued to the tach. I also have an rpm box to shift it automatically, wich I also know how to set now

Good luck at the track.

Where is everyone mounting the shift light ?

Thanks Shenoyp

I haven't mounted mine yet C_Henry. I wanted to get it working first before I mounted it. I'll let you know. It's only one inch in dia. shouldn't be too difficult

Between the shield and the guage cluster, just use two sided tape to hold it on. Mine has been mounted like this all year.
