New here, Turbo Caravan harness question

[VanBooster]

Hello, nice forum you have here! I have a '90 caravan SE 5-speed (a-523) TBI, and this weekend I'm going to part out an original (and rusty beyond repair) '90 turbo 5-speed. pulling the wiring harness and computer successfully is my first priority, but though I have a chilton's manual I am having a hard time understanding where the bulkhead connector is at the firewall, and how it comes apart. I don't want to screw it up. Sorry about no pictures, no camera at the moment. Thanks for any help!

Cake, drivers side firewall is a 60 pin connector, use a 8mm or 10m socket and unbolt it-its in the center and pull up, done. The wiring is snaked all over, going to the computer, lights etc but its not that difficult. It truly is plug and play with a TBI van. Just grab the computer too, the TBI one can't be made to work.

Fuel pump might be necessary. I have a 90 factory tbi/5spd that i converted to turbo with 90 electronics. It was easy. :)

Yeah, he has to change his pump, V6, same pump.

Now that i think about it, i dont know why i even said MIGHT. I remember my tbi pump wouldnt make more than 30 psi. It WILL need the turbo fuel pump.
