I still cannot find out if I can use A SOHC harness. I was told to use that harness in the OBD1 EG due to I would not have any extra plugs laying around. And there are 4 I have found so far. The only O2 sencer on the headers is not plug'd in and I am hunting down the plug for it. Also on the passanger side down low under the ABS pump-garbage I found a pretty big plug that is not going to nothing that I need to hunt down.
