wiring trouble

[sleepysilvia203]

i just swapped a ka24e for a ka24de and im have trouble connecting the plug under the fuse box in the engine bay (was said that it starts the car or something) so check this

the plug that i took off the ka24e harnesss is the one that fits it has 4 wires red/grey black,brown and yellow/green.. and the plug that im tryin to connect to the plug under the fuse box is the plug on the ka24de harness witch has two wires ...yellow/red and yellow/blue so basically it has diff wires and the plug is way smaller its just like mac2686's problem
