Re: vacuum questions

MAP should have it's own vacuum source from as close to the TBI as you can get. OEM used port on bottom of throttle body close to ignition coil. Are you using a stock intake?? If so, you should be able to utilize a vaccum tree on the intake (@ 8 O' Clock from the distributor). I think that these had a check valve before the brake vacuum canister. If you have to share vacuum, I'd share w/ brakes and transmission.
Power for the ECU... Can you plug in to a connection on your fuse box that is switched with the ignition switch? I'd be sure to fuse it. I don't know what you've got for an ECU, the '89 ECM uses 10 amp fuses for both the switched and constant power.
