I used the White wire after the tach filter. it is tapped up in your harness going to the coil.

Run it right off the coil, works best I feel on our non PCM cars (we're ECM remember). It's the white white, I'd tap in after the (what I assume is) a filter.

Though for anyone reading this with a 94+ it's PCM connector pin A13

There's 4 wires on the coil. I think it's 2 reds a black and a white. Either way, it's the white one

Might jsut be the bad pic, but that doesn't even look like the coil plugs.
