Default Damaged Megasquirt PNP help please.

Ok, I've trolled long enough, after being a member since '07. So I traded Braytonia for this ECU and I knew it was "fried" so I figured at worst I'd be out only a a small amount. So on to the problem.

After pulling both boards I found 2 burned resistors (R15, R16) and lifted traces. Actually I'll be testing the resisters with my DMM because it could be that the trace beneath it burned and toasted the resisters exterior but either way I plan to replace them. 2nd issue is that it had no cable and no DB9 which I had expected.

Question 1: What are the pin outs for the db9 on the board? Only pins 2, 3, 5 and 9 are used in the PS/2 connector.

Question 2: What mods do I need to convert this 94-97 unit to 90-93?

***edit***

I've replaced the resistors and run a jumper wire to bridge the broken trace. All seems good to go.

We've got the cables here:

You would need a new '90-'93 adapter board - unfortunately, they're not something we have in production any longer. A '96-'97 unit would also need a new case. Or you could repin the harness and use some sort of jumper to run the fuel pump.
