alritez first of all im driving a 98 civic hatch dx, which i believe its a obd2a, and im getting a ls motor and i want to know if i need to get the ls wiring harness, and my friend told me that i need the rear mount? and tranny mount? but from what car do i get it from?

and any other information that i would possible need would be great thanks

 

if it connects to the engine swap match it with the engine

 

Dont get the ls harness. You need to reuse your stock civic engine harness and modify it to fit the LS motor. Exactly how much modification will depend on what year the Ls motor is.

Here is alot of good info for your swap(including mount info):

you dont need to spend money on the ls harness, use the civic harness. the evap purge harness will need to be extended, and your iacv will need to changed/extended. you need the rear mount bracket from a 99-00 si, as well as the drivers side COMPLETE mount from the si (this included the piece that bolts behind the timing belt cover that the studs go through. b series axles/half shaft and b series linkage(exept del sol b16). that should be pretty much it


oh, one of the crank sensors needs to be rewired too i think, but im running obd1 so i didnt even bother with mine

 

wellz the motor imma get is from a 91 integra for free so yeah and the head im not sure what year that is from
