Please help - what are these and where do they go?

Postby mr2mk1hero » Wed Oct 05, 2016 4:32 am

Hi,

I'm finally putting my 4age in my MR2 mk1 back together, and there's a few electrical bits I'm not sure where to install.

Where does this bugger go? I assume somewhere near the alternator? I have two connections like this one. One is one the water temp sender, and I have connected the connector with the rubber sleeve to it. But I don't know where this other one goes. There's another connector that fits it near the one that with the rubber sleeve that connects to the water temp sender

Where exactly do I connect these ground points (MR2 mk1) (I know 1 goes to cylinder head, where the engine lifting hook is, the other one goes below the coolant filler neck bolt, but I have no idea where the third one goes).


Much appreciated thank you.

The ground, is that for transmission to body? I don't have an MR2, just throwing out a guess.

first one is for economic/power light in tacho.
doesnt matter where you install as long as tube on bottem can reach head and connector can reach it

Image 1 - that looks like something near the inlet manifold area, as the other side looks like it needs a vacuum hose to go onto.

Image 2 - that bolts onto the engine hook, RHS and the other end goes under the coolant pipe and bolts to the chassis behind the bracket that bolts the coolant pipe to the car. Hope that made sense. I have an AW11 so can send you photos if you want.
