Ok heres the deal I just finished up putting a 96 LT1 in my 95 firebird formally 3.4l. Heres a pic of the plugs im talking about.

Ok the harness of my 95 only has one of these plugs so obviously i need to get one m ade for a 96 with 2 plugs. This harness runs along the front of the car and plugs into the firewall. This is gonna get complicated now. I relaize i need a new harness here with 2 plugs like the one in the pic but will this plug into my factory v6 firewall plug. If not then I have the interior harness out of a 97 lt1. If i get a harness like the one in the pic then will it plug into the firewall with the 97 interior harness. This is confusing as hell but im sure somebody knows.
