Neutral Start Wiring - VY Series I/II

[dakardynadonor]

Hi all,
Doing a very slow Ecotec into Toyota conversion
Can someone confirm for me the wiring setup of the NSBU?
Do I have this right?
Light Grey/Blue from ECU to NSBU switch then Grey back from NSBU switch to Starter Relay
I take it the NSBU allows the relay to ground via the PCU when it's happy?

I can get the starter relay to throw when the grey wire is grounded, so it's working OK, just need to confirm the sequence back to the ECU, and I can't quite work out what the PCU pinout is telling me.

Thanks in advance!

Isn't there 4 wires?
I just checked a wiring diagram for vt s1. There is 5.
Look at yb35 that is the neutral start reverse switch.
Hope it helps

Yeah 4 to the NSBU but only 2 interracting with ECU I think. Other two are ground and reverse light trigger?

Look at the wiring diagram from last post.

Thanks Lex - confirms for me the ground is not in the switch but via the switch to ECU. Perfect.

I assume you are using the ecotec tranny?
