Hi,
i've fitted a 3S-GE engine from a 1997 mr2 into a 1990 shell (3S-GE came out). i have swaped the engine loom and ECU off the '97 engine into the shell but am not getting a spark. the engine turns over and is getting fuel but...

there is a white plug next to the ecu which i don't know where it goes to (probably the problem) any ideas??

the car has been sat on my drive for weeks now, would love to take it for a spin. any help would be great!


Cheers, Danny

ps. has any1 got wiring diagrams for the 2 engines??
