swapping 88 n/a with manual transmission from a convertible into my 87 n/a automatic that's blown. have complete wiring harness on the new motor but on the side that goes to the ECU there is no wire to run to what i think is the solenoid register.(has a huge yellow plug) on right front fender well. manual says that most models will have the solenoid register on that spot but apparently not an 88 convertible. i have nothing to plug into it with the new motor. my question is two parts. A: how important is this solenoid register to the 88 motor ( i don't relly even know what it does) B: does this solenoid register have something to do with the automatic transmission or something (I HOPE) cus' then i don't need it. anybody with any experience you're help would be gretly appreciated. thanks

 

i just discovered part B for myself. resistor is for high vs. low impedence injectors. still not 100% sure if i need anything else in it's place but we'll see at start up.

 

84-87.5 will have the resistor pack. 87.5 and later won't.

If you are using the 86-87.5 injectors you will need the resistor pack. If you are using the 87.5 and later injectors you will not need the resistor pack.

 

car is running great. manual trans is fun. (did trans swap too). this forum is awesome. thanks for everybody's input. i must have done about 300 hours of searches too and all the information is there if you can find it.
