I have a question, so you cut the green and blk/red wire, then you solder them together. What do you do with what's left of the green and blk/red wire that is still attach to the ECU clip? Do you just tape them up with everything or what?

Performed this mod on my stock SC400 before I performed the 1JZ swap - Worked Great No problems (even though the car was fine)
***Now,after the 1J swap - The pump for some reason Runs even after I've turned the key off.Same with my SAFC.Still Power going to both of those items.I have to disco the Neg Terminal to turn it all off...and then it goes back like the car was never cranked.
What would cause that? Meaning there must be a relay or something involved causing the Pump and SAFC to stay on after the key is off & out.

My issue? Works like normal but power still somehow keeping the pump running and safc on after the key is removed.I even tried unplugging the duel pump ecu and it still stays on.it weird.didn't do this the day before...and I didn't touch anything.
I don't have my interior back together yet to see if the radio will stay on or climate stuff so can't confirm "everything" stays on.gonna check se stuff nut anyone have any ideas would be great.

when i pulled my motor out my crank was f$#@ed i thought it was a crankwalk but now it started to do it again .I've replaced the block but it started doing the same BS again.
I will undo it when i get home and see what happen , i've never had this issue with my SC300 with 2JZ.
It just fills my cylinders with gas,I will let you know what happen.

Well mine ended up being a grounding issue. As soon as I ran another ground from the battery to the body of the car it works like it should now. It was backfeeding through a ground somewhere.
Before I did the swap it worked fine with the v8. Weird.

This Mod worked great for me. My car wouldnt start and when I looked into it the fuel pump wasnt working. i read this thread and followed the instructions then like magic my car started right up.
