95 Buick LeSabre with about 3K miles on a freshly rebuilt engine.

Check Engine light is on
Code: PO341

Replaced the following:
Cam sensor
Crank sensor
Computer
module
Coil Pack

About the only thing not replaced is the wiring harness section that connects the coil pack, cam sensor, & crank sensor to the main harness going to the computer. Any ideas or a good place to get this wiring harness?

Thanks!
