The loom man doesn't get involved in car looms just ecu looms at the mo as is very very busy, but he suggested you contact autosparks.co.uk, saying they are very good and good prices too.
Whilst on the phone to him discussing the connection point between the ecu and main car loom, he did confirm that they all connect in roughly the same place, but some have a 9 way connector some a 5 way etc so seems there is a bit of diversity.
He's just in the middle of moving at mo as well, so stretched time wise even more.
