Engine swap with different cam sensor locations

[clyde01]

I replaced a blowned 97 2.0L turbo engine that had the cam sensor on the rear of the camshaft with a 99 2.0L turbo engine that has the cam sensor on the front of the camshaft. I sliced the front cam sensor connector into the 97 wiring harness, connecting like color wires together. Had to swap ignition wires at the coil to get the engine running because 2 & 3 were firing when 1 & 4 were suppose to. Tried swapping the red and black wires while leaving the striped blue wires connected on the cam sensor wiring. Put the ignition wires to normal and started the engine. It started but did not run well. It appeared that it wasn't receiving a cam sensor indication and was running in a degraded mode. Can anyone help with this problem of swapping engines that have different cam sensor locations?

Maybe check the timing?

Maybe the sensor has to be adjusted in the opposite direction?

Here is a semi-related article.
It sounds like you already did the change of the plug wires, but it mentions something else with splicing the regular wires.

Good luck....

Thanks for the links. I set the timing mechancially and rechecked it. It is my understanding that the computer makes the necessary adjustments after that. It appeared to me that the front cam sensor can not be rotated 180 degrees like the rear cam sensor can. I was going to do it until I saw that the sensor and mount could not be rotated 180 degrees on the front camshaft timing gear. The screws would not line up.
