1989 mustang sbc/700r4 to LM7/4l60e swap I currently have a sbc 355 mated with a 700r4 and i was able to get ahold of an 2004 tahoe 5.3 w/4l60e. i already have the AJE k-member. i will be fabricating x-member if the one i have doesn't fit. will be using stock 5.0 fuel pump for now. my question is how do i wire the PCM to mustang existing wiring so that i can turn over the engine? would i need to hack into the black and grey connectors found on the driver side fender?
2004 LM7, 706 heads, 4l60e, everything included $800.00

Looks like the LM7 is a non-return line fuel system? Does anyone have any write-ups on how to repin the PCM harness to eliminate what i don't need? can i run it without o2 sensors? can o2 sensors be eliminated in a tune since technically they don't work at WOT. What DBW pedal assembly can i use?
