Is there any difference between an OBD1 d15b7 and OBD1 b18b1 harness? I'm trying to figure out which this is & whether it's auto or 5 speed.

 

It's an obd1 d15d7 harness. If it was a d16z6 or b18c1 harness it would have VTec plugs and the b18c1 would have an extra plug for Iabs.

 

Thanks. I wanted to know if it was a D15B7 OR OBD1 B18B1 (NON VTEC) though...

 

It looks like a '94 - 95 D15B7 harness, '94 - '95 LS MT harnesses are exactly the same except that the wiring going to certain connectors is longer and the plastic section around the fuel rail is different. An AT LS harness will have some extra plugs for the automatic transmission, AT and MT D15B7 harnesses are the same, '92 - '93 and '94 - '95 are different though.

 

Ok, thanks!
