Alternator Upgrade Question Regarding Adaptor Harnesses

[DoctorMuffn]

I've been doing research for the last couple days on the 280ZX alternator upgrade in a 240Z. I've got a '73 240Z and I'm first and foremost curious if Zs-Ondabrain (Dave Irwin I gathered) is still supplying the wiring adaptor for this particular upgrade. I sent a PM, but since Arne's post relegating that responsibility to Dave Irwin was from 2006 (and I'm a bit pressed to get my car running again) I figured it best to double check here among the general membership as well.

Another query I had:

Are the alternators from ‘79-80 different from the ‘81-83 280ZXs?

MSA sells them now. I think I'm using an 81 unit 60amp and it works great. On the 73 you just need to deal with the fuel pump realy issue. It's and easy fix, some wire, a Bosch 20 or 30 amp relay and about 20 min.

You can also make your own. Vintage Connections has the right connector available. That's the way to go if you want to work on crimping skills. Otherwise, your PM to Dave should work just fine.

And it did. Dave still does offer them. Thanks for all the responses. I'll look into the wiring modifications I need for the relay/fuel pump if I find an issue. The original pump has been removed and disconnected since I've owned the car and I've hooked another generic pump to the green wire coming from the black with white stripe (switched on) ignition fuse. It's been working for the past 2 years so I expect it's not causing my problem. There's that and I disconnected it and was still blowing that ignition fuse until I disconnected the T-plug from the back of my alternator (the externally regulated 240Z model).

Again, I appreciate the quick responses.
