Have a 2.0 DOHC I4 Sierra here that I'm putting a BOA into. I have another Sierra shell here already running a BOA so just swapping everything over, just want to know wheres the easiest place to disconnect the engine looms for the swap?

use the big plug, remove the complete wiringharness from the engine, usually there are a few plugs near the battery. I normally scrapped the shell (or used them on,  the dirt track ovals), and left the engine attached to the front subframe, together with the gearbox and lifted the shell over engine instead of pulling the engine out upwards, way to heavy! no need to cut the shell or anything, just loosen the subframe, the steering collumn, the fuel system (you could leave the radiator attatched to the engine, or loosen the hoses and get coolant in your shoes), the front stabiliser and the front struts.

iirc you could as Marc on this forum what plugs you need to disconnect, he knows a lot abouth the cables and such.

£ plugs on the bulkhead behind the battery join the car and engine looms together.  You need to pull the engine loom out of the bulkhead below the battery, this goes through to the ECU.  New engine loom is the reverse, feed the ECU plug through the bulkhead, hook up the 3 plugs behind the battery and you're done.  If the car has air con, then the engine loom also connects into the air con somewhere behind the centre of the dash.  If you can't find the plug then you can just cut the wires and tape them up.
Drive it like you mean it!

If the car is a mk2 facelift with the clear front indicators and smoke rear lights it should have 3 plugs behind the battery. For the early mk2 with orange indicators it should have 2 plugs behind the dash.
