Turbo to N/A swap ?

[BoostLess7mge]

i am in the process of swapping an n/a motor into my turbo shell so i have something to drive for the next few weeks until my other 89 is back from the bodyshop. it was to my knowledge that as long as i have a motor with cooresponding ecu and wire harness, i should be in good shape. of course little things like having to change the gauge cluster to make the tach work, throttle cable, etc etc have to be done... everything is just about done and i went to plug in the ECU, ABS and trans computer and noticed that some of the plugs are different. all plugs mate perfectly into the 3 ECU's, but there are a few other plugs that are left unplugged that don't mate up to anything. everything, except those few plugs, is hooked up. when i go to start the car it wont even attempt to crank over, could those few plugs be my problem? any other suggestions would be great! im sure ive left out some important details so i apologize...

Are the ECU and wiring harness of the same year? What about transmissions?

the motor, harness, and ECU are all from an 89, and they are going into a 91.

was the harness an auto harness? if you have extra plugs down by the transmission then it is... you have to jumper the park/neutral safety switch, even if you are using an m/t ecu.

both cars are auto so yes it is an auto harness. bypassing the neutral safety switch doesnt apply to me then right "fitoyota" ?? anybody else have ideas, or is this swap just not possible... thanks!

^^^^Anything's possible. Did you swap out the resistor pack?

i did a search for "resistor pack" and if im looking at the right thing then yes i swapped that over too. the only thing that is funny still are the few plugs that dont mate up right, in the glove box area, where the ECU plugs in.

im taking it that no one has ever done a swap from a pre-89.5 to a post 89.5 car that has a different wiring harness... theres no way i can splice wires by the glovebox area to make it work? any info will be greatly appreciated.

Following this logic, you might also want to think about having the size of your girlfriends tits reduced.

If I were doing this as a stopgap thing I'd leave the GTE electronics in place and just drive it, the ecu will just think it's not coming on boost and run fine.
