Tach Relay Wiring Help

[CosKev 16]

The only eng loom I could find for my ph2 309 Gti has had the tach relay wiring plug cut off

 

I've got the plug,and have matched up most of the wires colour to colour

 

But my question is,there are two light blue wires,and two white wires,does it matter which way round they go????

 

Or can they be connected to either one??????

 

Thanks

Is it like this one ?! :

 

 

... this one is from Ph1 Jetronic car which had tahco relay , since yours is a Ph2 then i suppose it'll be Motronic which has double relay system (injection supply relay and fuel pump relay) .. i have one Ph2 Motronic car as well in my garage so i can pop down and make a few pics if you wish

Thanks for help

 

Tried it today and it started ok,its Jetronic but looks like its got more wires than that pic you put up

Haven't tried swapping the wires round to see if it stops it from starting yet,will try tomoz to see if its just luck I got them the right way around or if they can be connected either way

Is this the same for Mi's (3-row ecu) as i cannot recall having 2 relays in the loom a put together?

and as i am having running problems with the MI so want to eliminate all

 

thanks

No, at least not on the one or two I've seen.

 

They still have the two seperate brown & green (or black) relays in the black box.
