weber carb and motor problems

i have a basket case of a wiring problem , have an 87maz b 2000 ... with the weber set up what wiring do i actually need??? what can i eliminate ??? must i still use the computer in the pass kick panel??? any 1 have any pics of there webber install ???

There are some wires that run from in the cab out to the wiper motor. These are the wires that you need to keep. The rest can go in the dumpster, including the ecu. 

Oh yeah! In the Dumpster!!! 

everything that comes out of the pass kick pannel is junk like that huge cluster of wires can go    ??? i know i need the headlight / turn sig / wires ect but they run down the drivers side ...

When in doubt, unplug...Start...if its running different, Keep it! I have a 2.6 with a 38mm weber, all wireing except the distributor wire, oil sensor, temp sensor...GONE! Runs great

Theres a few wires in the passenger harness that go to the wiper motor.  other than that it all goes from that harness.
