Swapping a 94 GT 5.0 into a different chassis. Wiring questions.

I have most of the parts together to swap a locally purchased 1994 5.0 w/ T4MO and harness into a 1987 Merkur XR4ti. I'm told that I should automatically go to a standalone engine control (Mega/Microsquirt) to avoid headaches. My intention is to keep the engine "mostly stock" so dropping $1000-$1500 for the MS and a wideband and anything else it might need seems like a bit of overkill.

How difficult is it to actually wire the SN95 harness into another car? Are there any pointers for making that happen...easily? I do plan to delete the EGR and the smog pump which looks like guys with 94/95 GT's are doing with little hassle. It wouldn't be difficult to do those on a swapped engine, right?

Also, is this a good forum to discuss this? If not, which one is better?

I dropped a 1992 Thunderbird 5.0 (same as SN95) in to a 1987 Ford Ranger. I used a Ron Francis Telorvek kit and a factory Mustang A9P with my manual transmission. Truck has run great for years now. Though I'm getting ready to switch to a PimpXS because I'm installing AFR heads, Cobra intake, etc..

I deleted all smog equipment. Smog pump, thermactor system, EGR, etc.
