Default 2000 LS1 engine harness on LS7 possible?

I have a 6.0 alum block and have a chance to get a killer deal on some cnc LS7 heads and intake. I'm set up for a LS1 Camaro harness 2000. Will my harness work or is it even close. I think the inj harness ends are different but not sure about the throttle body and coil connections.

I think the best course of action would be to use the cable TB you should already have with one of the various TB adapters. The injector adapters are also available. My guess is that you can use your LS1 coils and brackets on the LS1 valve covers. What year is your block? Is it 24 or 58 tooth reluctor? The LS1 PCM is set up for 24. The early LS2, 05 06 GTO is 24tooth.

The only things different would be inj, throttle body (electric), and possibly the map. Since you are using your old block with 24x that would not change, nor the coils. Steve

Glad I asked. New motor is 58. Is that something I can change to 24?

ok thanks for the info. looks like I'll leave it a 58 and try to find a harness that isn't fly by wire t body. I was told use a truck harness. Oh and the other thing, I need to slow down. I have LS3 CNC and hand ported heads. So hmmm I need also a LS3 intake lol. So much easier when it all was LS1 a few years ago. This car was done about 8 years ago when it still was new to do. Now I'm doing a super clean black 89 coupe
should have received royalty fees from AJE as we where the ones giving them the dimensions on using the 4.6 k member with LS1 mounts and then noticed 351W headers worked with LS1 flanges lol.

should have done my homework, upset here. I see that with a LS3 intake I need to find a throttle body with cable, There all so expensive unlike the ported one I had. So what other models can I use, LS7? Also the intake doesnt have provisions for a throttle bracket. I should have gone with the cathedral heads so I can use a LS6 intake or just bought the Iron 6.0 that had 24 reluctor wheel and all would have been good lol.
