I'm thinking about converting from OBD0 - OBD1, but my main question is how do I read any error codes if the OBD1 ECu doesn't have a LED blinker on it?

 

blownhatch harnesses have a way to do it. talk to him

 

im going to convert myself soon too i have his harness (blown90hatch)

Ground D4 on the ECU. It will cause your CEL to flash in your instrument cluster.

 

You jumper the connector under the hood on the passenger side shock tower - the one that you're supposed to jump when you're checking timing.
