Tach signal
I have a 89 iroc with a 94lt1 out of a vette swapped in. I installed the dakota digital VHX system everything is working except it will not pick up a tach signal to set up. I used the white tach wire from under the dash. Has anybody had this issue?

Make sure there is still a tach signal on that White wire after the swap, by temporally hooking up a known good tach to it.
