How to check engine codes

[eja]

I have the chilton manual for my 94 tracer. It tells me to connect a jumper between the self test input and the signal return pin. The only problem is that it doesn't show where the self test input (STI) is. It show it located off of the EEC. Anybody know where the STI is located or what it looks like?

Thanks

What's the engine size? 91-95 the tracer came with 1.8L mazda engine that had a 17 pin mecs connector or 1.9L engine that uses a ECC IV connector.
