AIrbag problems B1877 - For drivers Seatbelt pretensioner
Spent all yesterday afternoon Checking & rechecking everything & still get DTC B1877
Seatbelt pretensioner itself is fine - 2.5 ohm as it should be. Wiring checks out ok, except when pluged into seatbelt no reading at all
After inspecting the internals in the plug, there's a capacitor fitted !
Plugs for seatbelt pretensioners on 2009 onwards connects have a Ferrite inductor (choke) instead
Plug at the top is from my 2007 connect body loom

Only solution to solve problem, is to change seatbelt pretensioner loom to 2009 onwards.
Luckily I managed to grab a intact wiring loom complete with plug for seatbelt clasp (seatbelt reminder light/chime) from local breakers from a 2011 connect
Ideal part no wiring involved simply plug & play

Bigger bonus finally bagged the forward section of brake pipe from ABS pump to rear - which Ford no longer lists
Also vac pipe to brake servo with T-section for Throttle shut off valve - another part Ford no longer supplies (revised version does not have T-section)
