Astra Mk4 Towbar wiring | Vauxhall Owners Network Forum Apr 04, 2014My wife has recently bought a W reg (2000) Mk4 Astra and I am about to fit a good but second hand Witter towbar. I have been told that there are marks in the boot where the holes need to be drilled to mount the bar but I am wondering if anyone knows if there is an easy way of wiring Vauxhall Astra Towbar Wiring Kits - PF Jones Ltd Vauxhall Astra Towbar Wiring Kits every towbar needs a wiring kit, vehicle specific dedicated electric kits, 8100+ reviews, rated Excellent, 7pin and 13 pin kits Vauxhall Astra H Sporthatch (2005 - ) - 2006 1.6 Tow bar Oct 26, 2008Vauxhall Astra H Sporthatch (2005 - ) - 2006 1.6 Tow bar electrics?????. Fitting a tow bar to my 56 reg astra hatchback. The tow bar is a simple enough job to fit very similar to my 2000 astra, but the electrics are a bit different. There is a panel in the boot on the n/s/ when opened there is a small fuse box and plugs with one empty space, is this for the tow bar wiring?
