TBI Wiring Question

I have a 1991 Dakota with the weak suck 3.9 TBI engine, and would like to swap the TBI 318 from a 1991 full size donor truck into it. Question is what wiring dilemmas am I going to run into?

Also wondering about adding an E-brock Torker 340 intake, Holley Pro-Jection throttle body, and some dual exhaust. What cam should I consider? Truck is 2wd and will be a parts chaser with attitude, has the A500 trans, and will have 4.10 cogs. I'm new to injection when it comes to anything non-stock. Any and all help is much appreciated.
