Gonna break window.. :(

I replaced my old solenoid with new one, all my wirings good, took me 2 hours to get right tension, and went thru 5 feet of cable shit and alot of clamps...finally got it right...so i thought, tested it like 100 times, parked my truck, went to open it once more and its stuck...tried everything...getting the hammer tomorrow after school.

any tips how to get rite tension?
