MurdoMac 0 Posted January 15, 2014 So I have a new oil pressue gauge (1 to 7 bar) can I just piggy back the wire to the gauge of one of the existing senders? or do I need to put in the gauges own sender, T-piece etc? and if I can piggy back it, which is it? thanks :) Quote Share this post Link to post Share on other sites
fendervg 32 Posted January 15, 2014 AFAIK you need to use a T piece and sender, or you can get a 2 pole sender that does both the low pressure warning and drives a gauge. Mostly found on Audi Coupes with the 3 dial aux gauge panel. I did mine with a VDO sender and a connecting piece that has the existing pressure sender sat on top and the new sender to the side.
