Hi,

I am swapping an 02 VVT engine into my 90-93 MSLabs Basic Champcar. As I plan things out for an adapter harness that will run in between the Basic 90-93 ECU to the stock 02 Engine Harness, I'm currently stuck on 3 items.

Can anyone point me towards which pins on the Basic 90-93 ECU correspond to Inject C (02 Harness 2J), Inject D (02 Harness 2D), and Inject H (02 Harness 2N... VTCS)?

Apologies for being a bumbler and not being able to figure this out on my own. I appreciate any help.

Edit
Worth adding that the entire original 1.6 harness has been removed from the car, hence the usage of the stock 02 engine harness and the need for the adapter.

 

Per Rev (thank you again)

90-93 MS Basic ECU doesn't offer the InjH output, so the answer is to use another programmable output, like Fidle, IAC1, or Nitrous2.

I also re-learned that sequential injection accomplished by following these instructions. So pins 2Y and 2Z on the ECU will then lead to 2J and 2D on the adapter housing.
