Trans Am guys with Shift Lights?
but it wont work!
tach wire to #10 pin, white wire on the pcm (red)
12v keyed
ground, easy
it lights up, blinks the settings back, but wont come on at the rpms, i've tried several rpms, mainly 1000, 1500 etc
yes it was in 4 cylinder mode....and nothing
checked the voltage at the connection at the pcm (which is sodered) and got 0.030VDC (or close, can't remember)
same voltage all the way up to the shift light, but nothing is working??
Can't get hold of Harlan, so what do I do? can I tap into something else and then use a different setting?
