Hey guys I'm doing an LS2 swap and had a question regarding the reverse lockout on the e40 pcm. I'm about complete with my wiring and I have 3 wires left for reverse lockout on my t56. I have a yellow off of c1 for reverse lockout control and I have a yellow that was on c206 I have labeled reverse lockout and also a pink/light blue off c101 labeled reverse lockout. I'm guessing I've got both wires from the solenoid and a relay control wire from the c1 on pcm here. Does this sound correct?

Here's what I'm thinking.
An ignition hot to relay
Pink/light blue from c101 to N/O side of relay
Yellow from c206 to ground
Yellow from c1 to trigger relay

Can anyone verify this is how it's intended to work?
​​​​​​​All my previous swaps never used a reverse lockout relay.

PK/BU is the IGN feed to the solenoid. YE is the control that goes to the ecm. You can use a relay if you want but it isn't necessary.

Interesting! So the pcm goes to ground to control the lockout much like the fan control?

Correct
