#4In first post i mean the mk2 vts the earlier ones still had the single plug ecu didnt they well was the loom different from the mk1 to the mk2?
-
#5o a vts, not to sure then

#6Forget about mk1 mk2, if its single plug its same as all singles, if its triple its the same as all triples.

#8Yes there a three looms you can have...
1. Single plug
2. Crossover
3. 3 plug
The single plug loom is the original mark 1 loom, single large ECU connector with the two smaller connectors to join to the interior loom.
The crossover loom as its nicknamed is found on very early mark 2's made in 2000 (but not all just random ones it appears), these use the same large single ECU connector found on the single plug looms, but have the large single connector found on the passenger inner arch. These looms allow a single plug ECU to work a 3 plug interior loom (for digi dials).
The 3 plug loom is the common mark 2 loom and has the 3 small ECU connectors and the large single connector on the passenger inner arch, the same as the crossover loom.
If you need any more info regarding the crossover loom, and particularly 3 plug loom to crossover loom swap, PM me as i've put a lot of time and effort into researching whats what, should find out if i've got it all right this weekend

Top = single plug crossover loom. Note the locations of the pins(well try), 3 plug uses the same connector with a different pin layout
Bottom = standard single plug vts connector -
#11ok well i've got a 16v engine but having trouble getting a bloody loom for it coz the connector on the throttle body and map sensor dont fit? its a single plug engine and my old engine was a single plug too so if i look at the piks above find out which one is on the loom that doesn't fit then its the other one lol?

#12Fogot about the cross over loom. Although the single plug loom i have dosent have 2 connections to the interior loom.

#14The map sensor changed from year to year, the TPS should be the same unless you had a 3 plug one.Quote:ok well i've got a 16v engine but having trouble getting a bloody loom for it coz the connector on the throttle body and map sensor dont fit? its a single plug engine and my old engine was a single plug too so if i look at the piks above find out which one is on the loom that doesn't fit then its the other one lol?
