knock sub harness, rough start

[hungryjoseph]

On the series 1 rb25, I've figured out 2 of the wires on the knock sensor sub harness go to the knock sensors, the other 2 go to the air regulator.

what do the last 2 wires go to?

I've been having issues with long starts, the motor takes forever to turn on. I have to blip the throttle and crank it over 3 or 4 times. It does it both cold and hot. Also breaks up at higher psi (12 psi) and rpms. I have stock turbo, greddy style plenum. Once it's on it idles and rev's fine. Doesn't misfiire during idle or revving or regular driving.

I don't have the knock sensor harness plugged in, only the knock sensors are wired directly to that plug. I don't have the subharness. Could it cause this problem depending on what those 2 other wires go to?

The other 2 wires are to the shielding over each knock sensor wire.
