3500 in a P'up

[Canyonero]

I think the ECU you'd want is a 1227730 (in-cab) or 1227727 (underhood) - same ECU, different packaging. Those seem to be the preferred engine-swap ECUs. But I'm not sure that's what the '94 Cavalier had. I have a '93 Cavalier Z24 with the 3.1L, but I haven't found the ECU yet to check the numbers.

These are the same ECM: 1227730, 16196344, 16198262. The 1619 numbers are later service numbers, but internally the same.

Thanks for the help. It would appear that the in-cab unit is what I need since when I trace out the known engine connections they go through a molded bulkhead fitting. Does anyone have one for sale? O'reilly's are about $100.00 w/no program chip. I'd need that as well.
Question about CPS cable. My harness has a pair of wires per the schematic (PPL + YEL) with 2 pin connector (female) that fits the CPS sensor that is bundled with the injector wiring. I find that the ICM has 3 ports, all male, a 2 pin, 3 pin, and a 6 pin. In the harness there is a mating 6 pin female that fits with 5 wires. The harness has no 2 pin connector that fits the ICM. Any ideas?

Just a curiosity, what parts have you already accumulated for this swap?

Since I have a whole Cavalier (wrecked but drivable), I probably have the bulkhead you're asking about, but I might actually want to use it for myself. I need to take inventory of all my bits.

My workshop will be finished soon, sheetrock and paint should be finished up this coming week, then I'll unpack all of my parts... I think I may have a Lumina harness with both sides of a bulkhead connector (not sure if it's the same style), it's been a long time since I've had it unpacked.

I have an LX9 with 'all' the parts, except the wiring and ECU. It is out of an '04 Malibu. The harness that I have is from a '94 Cav V6. I have the schematic for the Cav but not everything matches, that is why all the questions. Definitely not 'plug and play'!

Did you find a 6x crank trigger?

Getting a billet pulley and CPS bracket from Mark. A little delayed, they were out of stock.

The 2 pin connector that fits the ICM will be in the main harness near the 6 pin plug. It will have two wires, a pink (ignition) and a black or black/white (ground).

[lilredtruck]

Got it, thanks. The yellow and purple go direct to the ICM from the CPS - correct? I will be looking for a wiring diagram/schematic for the '04 Malibu 3500. The EGR on the Malibu has different 'plumbing' so I have to keep it but the colors are not the same. Ditto the MAP sensor.

[Guest]

Yes, the Purple and Yellow cable, will actually have 3 connections at the ICM end, and only two at the CPS. The reason for this is there is a shield that is grounded at the ICM end.

The 3500 CPS will not be compatible with the earlier 660 ICM. You will need an external crank trigger for this set-up.

The EGR may also not be compatible with the earlier EFI. You may need to swap an earlier EGR onto the engine.

MAP sensor should not be a problem, just use the correct pinout.

[lilredtruck]

Understand the electrical problem with the EGR. So if I get a '94 Cav EGR, is there an adapter to convert the 3500 single port to the Cav two port? Note that the 3500 EGR is a 'straight-thru' like a water valve with an inline connection to the exhaust manifold, not side-by-side. Or do I just abandon using an EGR and cover the hole in the UIM? And have the new crank trigger and balancer from Marc, just can't get it on. Must be a trick!

Are you getting a new external trigger from TCE? I know he's been backed up quite a bit with his current health condition's and I actually didn't expect him to be making any more of those parts. Maybe it's just the DRTC's that are more expensive to produce that he required a large group buy to make more.

He probably have them in stock.

Yes, I got it through britishcarconv. The sensor is in place but the HB is not. Goes on about 1" and stops, needs to go another inch to stop flush w/crank. Maybe I have to heat the balancer to get it on. Shaft measure 31.5 mm, HB the same.

[3400-95-Modified]

The HB is a press fit, you need to use the bolt to press it onto the crank.

and John, a previous message stated he talked to Marc and they were out of stock so I found it odd that he is still making the external triggers and responding to BCC inquiries yet it's been months and months in between DRTC updates....
