1UZFE into classic merc, wiring help!

[dooleysl]

Hi,

Am currently replacing the 302 that was in my sl with an LS400 engine/loom. Possibly have a few bits of wiring missing, although it was meant to be complete.

Any help/ideas much appreciated. Have attached photos of car and the plugs and loom that I have.

yes u r missing the 4th plug on the ecu that powers it up and does some other stuff

all the other plugs u need to find what wires are needed and what they do and then cut the right wires and wire them up
its not hard some people on here say its only afew wires

Pictures don't seem to be working but as Sideshow says just trace each wire 1 at a time and it is pretty straight forward. A bit more than a few wires but plenty of information on this forum. Don't let the smoke out so take your time, good engine choice for the merc.

If u can't find that Plug I do have afew for sale
But wire colors will not match your ecu so u will have
To go by pin position
They are getting hard to find these days
Maybe try the person who u bought motor off

Do you know what year then engine ecu is ?

It looks like the pins from a 92.9-94.9.
