I did a fuse box relocation and in the process cut a wire that i think is causing cylinders 2 and 3 to misfire. There are three wires coming off the plug that connects to the coil pack. One of those wires connects to the blue plug thats on the firewall. Its simply there to connect to the black and white wire that connects to something else. I need to know what it connects to. I think I might have taken the wire out in the process of relocating my fuse box. If anyone has a engine wire harness lying around they can take a look and and let me know what the black and white wire connects to. Please take a look at the pictures illustrating what I mean. My Car is a 98 eclipse GSX manual.
Snowboarder714 or anyone else that's done a wire job or anyone that can look at there engine harness, I'd be real appreciative if you could help with this issue. Thanks.

Ok awesome! I'll take a look at that.

The wiring on the car was junk to begin with when I bought it. Pin 1 from the PTU was cut and the car ran fine, even though that pin is supposed to be the output to fire 2,3 coil primary. I didn't think anything of it until now. Could they both be running off pin 8 wire for output 1,4? Thats what Im gonna try tomorrow. Let me know what you think otherwise. Thanks.

Power Transister:
Stock (2g) 8 pin connector wire colors:
pin 1: blue-black (output to fire cyl 2,3 coil's primary)
pin 2: brown-red (input from ECU to fire cyl 2,3)
pin 3: black (ground)
pin 4: white (tach output to ECU and gauge)
pin 5: unused
pin 6: larger black-white (+12V from ignition switch)
pin 7: black-blue (input from ECU to fire cyl 1,4)
pin 8: black-white (output to fire cyl 1,4 coil's primary but leaves coil as blue-red going to single pin "engine speed detection connector", then from there to pin 8 here as black-white)
