4ktq wiring notes
Spent the day today going over the left side wiring harness and cutting
and labeling wires that I needed to splice in elsewhere or just plain
didn't need with Huw Powell. Seems like each time he comes over it costs
me a new part off my parts car ;-). His expertise is well worth the cost
though. Here are the notes that I wrote done during the process
verbose... might be a tad confusing... I even have trouble remembering
what I meant on a coupla things but hey that's ok ;-)
Anyway, enjoy the brief reading:
things to cut and notes:
Fuel economy sender (3 wires side of fuel distributor) Hook up later to
4k trip computer
Pin 13 Kostal connector T14 B cut white/Red wire
Pin 7 "" Green yellow wire to AC on signal
Pin 3 Yellow/black Unused
Pin 5 To board computer. White
Black/Blue wire on 4 pin connector Ignition on signal to unused unit
Black/Blue wires (3) on istrumental panel stuff.
Green/Brown wire from fuse box to washer system stuff
Blue/Yellow to multifunction sensor to ac control head
Blue/White to nowhere?? from multifunction sensor.
Violet/Black wire from instument cluster. is tack driver. Connects to
Red/BlacK/Yellow wire currently on 4k coil
Yellow/Blue wire from T14B to onboard computer.
Blue/Yellow and White/Gray wires from T14C go to oil pressure senders.
use existing 4k wires for oil pressure senders.
White/Blue wires to multifunction temperature switch (Bentley lists as
White/Black) come from the coolant low level switch and go to the
former coolant sensor wires from 4k hook up as follows to MC multifunction
switch/sensor: Blue/Brown coolant guage wire is fed from the Brown/Black
sender wire. The Blue/white overtemp wire is fed by the White/Blue sender
wire. The other White/Blue sender wire goes to the low coolant level
The Red/White wire that goes from the after run radiator relay to T14 D
(Kostal connecter 7) gets cut. Went to ac control head unit.
The Red/Yellow wire from the after run relay goes to pin 85 of the
radiator cooling fan relay which is a Red/Green wire coming from pin D85L.
Rewire radiator fan relay so it gets power from the battery and not from
X-relay (load reduction relay).
That's all for now. Tune in next week for more fun ;-)
