1990 735i
This item seems to have heater pipes running from behind bulkhead - do I need this?

And secondly................

Is this a main power lead?
I'm not a mechanic but am rather bravely (read stupidly) tackling this conversion alone!
I already have a list of bits:-
Using auto 735i engine 1990 (bargain ebay find £25 whole car!)
e30.de mounts p3
324td fan and clutch (anyone fitted one with pics showing clearance?)
e28 535 manual rad
e28 gbox
e28 flywheel and clutch (525)
m3 prop
m3 exhaust
m3 lsd
Just spent my spare couple of hours these last few mornings removing exhaust, prop, disconnecting accel cable removing rad etc...
Just need to separate the fuel lines, the power steering fluid reservoir and unbolt engine mounts and the big 30 will be ready to be lifted.
Pls help
