ACCURATE 90 t2 Schematic

Does anyone have an accurate engine harness schematic for a 90 T2? I have the FSM and it's not even close. As far as I know The harness is stock. Example
FSM page z-38 B2-03 1s should be a red with black strip but it's black with a red stripe and
1v of the same connector should be a blue wit a green stripe but it's actually a yellow with a white stripe. this wire should go to trailing ignition coil but it really goes to a single connector that's identified as a coil check wire.

How does the wiring compare with your other car? The 1991? Those should be the same colors going to the same item. Sorry, no series five car here.

Here's a jpg, I THINK from AllData, but I don't remember what year. Series five for sure though.

thanks hailers. I went to that site and found pretty much what I needed. I've spent 24 years in the Marine Corps as a Avionics technician and I have to say that vehicle schematics are probably the most nonsensical I've ever seen. I did figure out that there are some disconnects. None of the connectors on the harness have connector numbers on them so when you're trying to run down a wire it makes it a little more difficult.

Sort of like working with F-111 schematics/diagrams and then going to F-16 schematics/diagrams.

F-16 diagrams, on the whole, suck compared to F-111 schematics/diagrams. Good airplanes both, but they went backwards with the F-16 diagrams.

What Mazda did, that you probably won't come across since you have a series five, is on the early cars they gave a reference designation of X-15 to a connector b/t the Front and Em harness.

Then in 88 they called the same plug FEM-01 (Front to Emission harness). Then later, I'm almost positive, they changed the designation back to X-15. Go figure.

That plug is just an example of lot of other connectors. It's more than that one plug/connector.
