OK. Now that wiring is per the FSM, have you verified, that you’re getting spark on all four cylinders?

I’d try to help but without seeing or better understanding what you have, there’s not much else I can offer. I’m fairly surprised they don’t provide any install information.Once you get it figured out, it would be great if you posted back up here letting everyone know what those 8 pins ended...

That’s what it looks like. Yes, MT = manual transmission.Verify that your car is setup for California emissions (either check your vacuum hoses and compare against the Federal and Cali diagrams or check for an EGR Temperature Sensor). If so, MD128622 is what it should be using.

The one on the right has the correct case / mounting brackets for a 1G.That said, we can tell absolutely nothing from this picture otherwise. Remove the covers and take pictures of the boards or try some self-identification using the printed number on the white connector (inside the case)...

Reviewing the wiring from the original post, those extensions look correct. And that’s how it’s wired now? Please confirm.

Definitely possible. And I agree with Hiroshi on all points other than the 1G intake manifold — it could be used on the 2G head, but it will not be a good combination of parts.It would allow the car to operate but it would not be near any sense of optimal. Any of those manifolds he mentioned...

Do you have pictures of what you’re dealing with?Did OHM provide any instructions along with the harness?

It looks like the Haltech diagram is labeled opposite of the factory service manual. Normally, I’d say that’s not an issue but the ignition inputs and coil outputs are swapped versus what the FSM shows.Basically, what Haltech shows is their pin 8 is the FSM’s pin 1; their pin 7 is the...

Yes.

Figured it was worth a shot. Are you describing inverted flare fittings?2G Turbo feed line fittingsI don’t find any matching that description, exactly. But eBay does have this DIY option where you drill the 0.075” hole through.

Maybe a combination of items from FP? The filters have the restrictors.

First thing is first - check the level of the brake fluid in the master cylinder. The light being on will not cause the vehicle to operate in limp mode.Good thread for reference: https://www.dsmtuners.com/threads/ebrake-light-stays-on.36497/

It appears another ‘90 non-turbo transmission should be a direct swap. I cross-referenced part numbers for clutch, pressure plate, throw out bearing, fork, slave cylinder, and both axles against a December 1989 non-turbo VIN. They all match. The transmission for the December VIN, however, is...
