I took the engine shut off switch out first, and replaced it in the new throttle housing. Next I put the spring trigger on, put the throttle cable in the new trigger, placed the wires in the throttle housing,snapped the housings together and tightened the screws back to the trimmer. Everything works fine now. Thanks
