YJ /4L ECM on Cherokee Harness

Asking for some advise. I am swapping a cherokee 1996 HO 4.0L engine in my 1990 Wrangler YJ. The engine will be stroked to 4.6L as per "4.6L Poor man's stroker" receipt.
Question # 1: I bought a 1994 Wrangler 4.0L / (Manual Trans) computer (ECM). I realized after "winning" the bid on ebay that I forgot to check the plugs of Cherokee 1996 vs Wrangler 1994. The guy or "seller" tells me that the ECM will plug in the Cherokee Harness. It is correct? or no.
Question # 2: My actual engine (1990 258-4.2L) will be the donor for the stroker parts. I am interested to use all the front stuff (i.e P/S Pump, Alternator, A/C compressor etc) in the 4.0L block. I want to run the mechanical fan. It is possible?
