The MAS connector is a 3 wire flat connector with a magenta o-ring.

The VIN is correct, trust me. I have verified that it was an original 6 speed car.

Ok... Well I found the 3 wire plug then on the driverside. I was looking for a 5-wire plug as is on my 3rd gen TPI.

Like he said it was a 95 4l60e package and in the description it said the engine and transmission is good but I didn't get the transmission and my dad took a look at it when I had the k member to start the swap he looked and said it was for a manual transmission so I have to swap the wiring harness and ecu

Re: LT1 Engine Identification?

The 94/95 “ECU” (actually the PCM - Powertrain Control Module) is the same whether it’s for a manual or automatic. It can be flash programmed for either. The wiring differences are minor.

The K-member that supports the engine and front suspension is the same whether it a manual or automatic. Only the trans cross-member would be different.

If you plan to use a 4L60E, you must use a 4L60E that matches the program in the PCM. A 94 4L60E has a ”switched” converter lockup. A 95 4L60E has a “pulse width modulated” lockup. Later 96/97 4L60E's are not compatible because there are internal differences. The harness connector has a different number of wires between 94 and 95. Good reference post from another site:

4L60E year differences and interchanges.

Re: LT1 Engine Identification?

I have no idea if the (unknown) truck transmission is compatible with your application.

All you've said is your "doing a engine swap". What are you swapping it into?

The transmission came out of a 94 gm truck that had 4wd I had to that the output shaft from my old transmission and the tail shaft.
also I have a 95 Camaro that had a 3.4l v6
The thing's I know for a fact that u need is the fuel pump the wiring and ecu.
If there is anything else that I don't know about that I need let me know

And I'm swapping into a 95 Camaro it was the 3.4l v6 and I'm putting a apparently 94 Camaro lt1
I know i will have to swap the engine harness an potentially the forward lamp harness and under-dash harness.
Do you know what else I need to change apart from the fuel pump.
