^ Follow jose's instructions let him know what happens. I'm also interested in knowing whwat happens as i have a 1J going in and if i run into the problem i know what to look for.
All the ecu connetors are pluged in? right? All you need after that is that big grey plug to let the car start and run. If you have the Hydro fan connector plugged in to the body connector for the dash, the car will run but wont rev past 3K.
ok bro im doing everything u telling me and its realy making a diference,i unplug the hydro fan plung and the car runs better but it keep on shut it off wut else i need to,thanks for ur help
the car was hard starting before since we unplugged the plugs under the dash it runs better but didnt cross 3000 rpm we disconnected the fan like u said now it rev pass 3000rpm an higher but sometimes it wont start unless u play with the throttle an it back fires on high revs we got a print out for the swap from 1jzgte we followed all the steps for the fuse box an under the dash any suggestions
Well now those two plugs that look like each other must be plug in to the right place. It should be a no brainer, if the dash works its the right plug. Check all your wires under the dash/ECU area and make sure everything is grounded properly. Sometimes when you unplug the connectors to the ECU it will have a hard time iddling. All of your issues are in that area. Who ever did the wiring there messed up.
Im glad your Revving problem is fixed.

ok im gona be onest to u bro i did the wiring harness my self never did that my self man,but the car still acting funnie
Before you run out and buy a new ECU, try taking it to a TV/small electronics repair shop and ask about getting your capacitors replaced. Shouldn't be much more than $50
