I pulled my p28 ecu out today and was gong to put my new p30 in, just to get it out of the way. The plugs are different. I thought the plugs were the same for all obd1 ecu's? Can anyone explan this? The p28 is on the bottom and my new p30 is on top. Here is a pic of the sockets on the ecu.

EH6TunerDaniel

grayegcivic

What car is this?

EH6TunerDaniel

97 sol, but It has a p28 ecu. I figured it had a conversion harness. I guess they just resocketed it.

yea, when i pulled the ecu out of my car, it looked like the bottom one. its OBD2a. def not obd1 for your bottom ecu

Anyone know how to get the wire out of the plug to repin it?

better off buying an OBD2a-OBD1 conversion harness.

Best advise on the thread.

Top is OBD1. Bottom is OBD2, not the same!

just an FYI: 96+ Sols came with rare versions of the typical OBD1 ECUs. They are OBD2a plug'd with an OBD1/OBD2 hybrid internal setup. Unique ECUs.
