i have a 89 240 xe with the SOHC and im puting in the ka24de, but the plug on the end of the wireharness (under dash behind glove box not blue ecu plug)
is different then the one on the sohc harness!! what do i need to do to get this to work???
There are more wires on the soch plug then the dohc plug!


do i need to change out the harness under the dash also or can i just swap the pins into the other plug matching colors?
Or do they make an adaptor/jumper for that purpose?


any answers will be awsome!!! THX

you need a DOHC harness. no other choice.
