does any 1 have a picture of a manual box showing what each plugs job is ? i figure one is the speed sensor the one near the gear stick is the reverse switch but what is the other plug ?

Neutral switch

Neutral switch, i wouldnt bother connecting it.

 

nice one for that appreciate it!!!

also as i'm crap on computers..i can't find what i'm maent to do with a certain connector on ecu? which ecu? which connections? i've searched before and found it but can't tonight!

Connecting the neutral switch to a pin on the ecu, seriously dont bother. I did this and it advances the timing everytime you put it into gear and of course then raises the revs slightly. I got sick of this, so cut the wire at the ecu end i had connected and all good.

 

There is no detriment by not connecting it, so make life easy for yourself and dont bother, just my opinion though lol

if i don't bother ,will the car run and feel as a manual should? no issues?

Yep no worries
