got a little manifold I guess thats what you call it with the gauge, just had to buy a couple of fittings, so all installed and working. Early testing is promising, short run around town, 5 0 - 60 kph, few stops at lights max temp was close to 60c, on highway drops quickly to around 45 - 50 - this is return line from upgraded cooler, mounted cooler on passenger side figured fan will pull air through always rather than on thermo side would be something else I could forget to switch off or on.
I think with bonnet vent and highway speed a lot of air is pulled through radiator etc, happy so far, here is pic of gauge, no pics of install is similar to others just a t-piece into trans line.
