Does anyone know where to find a pin diagram for a 1999 ecu. I am trying to convert my 99 computer to a 96 computer to do away with my immobilizer and to also be able to use an aftermarket ecu.

I am am also looking for the diagram for the clips that go into the dash harness, as well as connectors for the fuse boxes under the hood.

I am purchasing a 96 engine harness and ECM, and I'm trying to make this as easy as possible before i do this.

Thanks.

Well EC108-115 has the FSM version, but like I said, it's not completely correct.

Assuming F36, F37, F102, and F104-109 are the same, then it shouldn't be a problem.

Now that I look at it, F108-109 are for the TCM, so those aren't relevant.

Here's a list of everything that is on the '99 that isn't on a '98 and vice-versa, this doesn't really help you in any way since you are swapping harness', but I'm posting it anyways. The '98 one might be missing some because it wasn't based on the diagram, only that stupid chart. The are also missing 46/44 for cps.

1999-

17--Immobilizor

35 & 36-- egr volume control valve

53* swirl valve

57* rear o2

68 - a/t comm.

105* rear o2 htr

* = cali

1998

6 - a/t diag line

11 - fuel pump relay

22 - p/n switch

27 - evap purge #2

65 - a/t signal 4

66 - a/t signal 5

73 - a/t signal 1

74 - a/t signal 2

77- a/t signal 1

103 - egrc selenoid valve
