Anyone good with wiring?

[901Tahoe]

I did a body swap on my 02 tahoe switched everything over to an 03 denali. The chassis harness during the swap some how got cut. So I've rewired it to the best of my abilities but crossed a wire somewhere so now my left turn signal has constant power (doesn't flash just stays on) and have no brake lights. Does anyone know what I may have crossed or does any one have a wiring diagram for the chassis harness.

google wiring diagrams, there is lots of info out there , retrace the work that you did and i'll bet you fill find your mistake, remember every thing is color coded. good luck!
