Bearing in mind that I am a complete novice. I would like to install 3 VDO gauges. I know where I will put the gauges in the car but need help in choosing the right ones to make an easy install. 1st, Oil pressure gauge, Can I get one that will splice to a original sender on top of the oil filter housing? Right, regarding oil temp...I will leave that to the MFA. Water temp is indicated on the clocks (well, sort of) So 2nd, Volt meter (naff, i know) 3rd, Lambda, Air/Fuel mixture...I know this one will be a bit expencive if I want a good one. Any help will be much appreciated. Thanks
