So I’m able to jump the blue connector of the OB1 but I don’t have a dash board. My question is where on the fuse panel or equivalent would I be able to wire in a light to see my codes. 1993 Accord. F22A6. Thanks!

The wire coming from A13 at the ECU is the MIL light. I just can't remember if it is power or ground, so I am unsure what the other wire on your bulb would need to go to.

the ECU provides ground, the other side of the light needs to be connected to battery.
OP, it's a simple light, even a 12v LED works fine. It can be mounted anywhere you have available, next to a switch for the service jumper ideally.
Dammit….should have mentioned this earlier but just remembered I have an ECU from a 1993 prelude. Same engine family so I would assume the pin outs should be the same.
Last question….maybe. I have a battery disconnect switch that shuts off power to the ECU. Essentially the whole car. So when I power it back up I assume the codes are all reset? If that’s the case do you recommend running a wire direct to A25 from the positive terminal of the battery? Any other suggestions. Thanks.
