s14 sr into 97 240 need help with wiring issues
 

i have the engine harness out of both my 240 and clip, but i noticed that the boost pressure sensor wirirng drops through the junction block and into the loom in the fender well. do I cut the wires, pull them through, and trace where they go to rewire? do I eliminate the sensor somehow? or do i need to cross over all that extra wiring and that junction block?
also there is an 8 wire connector in cabin on the 240 harness i think it heads back to the evap system but cant find it in the fsm anyone familiar with this its a 97 240 by the way

appreciate any help thanks
