So I installed my 1980's HKS timer following instructions in my previous post (thanks Spike) as well as some searching. Here's what I did:
Edit: Actually, I wired it differently from what Spike posted, here's what he said:
wires for turbo timer
the gray wire you do not need for cars in USA
wires for the ignition harness for miata.
And here the wiring I used:
Timer Blue to harness black/red stripe
Timer Green to harness blue
Timer red to harness white.
Ground to hole on steering column (checked the ground it was good)
Started car, turned it off, car turned off :(
I noticed there's 2 all white wires, did I tap the wrong one? Thoughts?
*edit* I tried the other white wire also, no dice. And according to the above link, one of the white wires has blue diamonds on it?? I didnt see any. But regardless, timer powers on, but its still letting the car shut-off right away.
