Quick wiring harness question

[DMB-87Supra]

I have a wiring harness that should be from an '89 Turbo Supra. How could I verify that it's a turbo harness and not an N/A although I'm about 98% sure it is? Also, the bigger question is how can I tell whether the harness is from an automatic or a manual. I'm assuming there'd be an extra connector(s) on the auto? If someone could lend some help as to describing how to go about figuring it out, I'd greatly appreciate it. Thanks in advance.

A turbo harness will have 5 pin connector for the AFM and I think the N/A has a 6 or 7 pin for the AFM. The auto harness will have a few extra round plugs by the egr vsv plugs. The M/T does not.

Thanks a bunch, I'll go take a look for those connectors then. I greatly appreciate it.

The Turbo harness also has two knock sensor plugs. NA only has one.

Kinda related...what's the dif in the auto-manual on the ecu side of the harness!

I'm also under the understanding that you can use an auto harness in a manual car..?

Auto harness will have an extra plug for the auto tranny.

For a manual car, you can use an auto OR a manual harness, and an auto OR a manual ECU.

For an auto car, you MUST use an auto ECU AND auto harness.

Just out of curiousity, would these be the plugs for an automatic trans or?

Thanks in advance.
