In Topic: How to Wiring Mackay MS3 harenss....???

Yes i have the Mackay harness. It did not come with the 240sx TPS. I had to buy and modify one to fit. I did not use the factory fuel pump and efi relay.

 

I had previously done a l28et swap with stock harness and ecu on my 280z, so the MS3 harness and ecu was basically the same install. See if you can find a l28et swap guide for a 280zx, it might help you to see visually where connections are made.

Ahh, i just noticed you had a 280zx and not a 280z. I'm not familiar with the zx. I would suggest following the wires from the "ign. lock" and see if they go to a connector.

 

Sorry i couldn't help more.

Look under the drivers kick panel to the left of the steering column.  There should be a white connector with four wires coming out of it, Switched 12v, Constant 12v, Fuel pump and Start. Use a multi-meter to verify. Unplug the connector and use the hot side of the connector to power the appropriate relays. 

 

For the TPS you will have to make your own connection, the wire should be labeled. If not hook everything else up and it should become apparent which ones they are.

You'll get there buddy. It looks like your on the right track. Just be patient, these guys are really trying to help you out. Try and answer all their questions. Look up "trigger offset wizard" to understand more about MS and timing. You need to know a little more about how MS works. Did you ever hook your wide band up to MS? Did you do a data log?
