coolant temp sensor wiring WBX, 85 vs 86

[wcumbriangasman]

just wondering how easy or difficult it is to make the 2 wire black coolant sensor from the 86 WBX on, work with a 85 van which has only one wire going to the coolant sensor. I'm certainly no electrician! so need help. The reason I need to know is because I'm in the process of putting a second hand 86 WBX in my 85 van. All the 86 plumbing hoses came with the engine so the plumbing side is sorted. thanks

86...two wires ones an earth...

thanks for that, hopefully with a bit of luck shouldn't be too hard to wire up then. The blue coolant temp sensor for the ?choke/manifold heater next to the black one also has 2 wires. Is one of these an earth aswell? thanks

no that is a little more complicated

are the 2 wires connected to the blue temp sensor on 86 and on vans the same as the 2 connected to the 2 spade terminal thermoswitch on 85 vans. thanks
