ok without hacking up any wires first i've managed to connect the indicators into the circuit to check they work and they do, tried it with the resistors and agree with you, they are shyte... although neither my mechanic nor I can work out why there is a male n female wire coming out of either side of the resistor, we can't see what their idea is with that. The resistor isn't slowing down the flash rate, its just making the resistors dimmer. I've found instructions on how to wire in a new relay...

thats the address for anyone else in the same position as me... but I'm unsure as to what relay I would need for it, i'm guessing it would be a 2 pin thing and just wire it up as the diagrams show in that link. Do you know what relays would be best for doing this job and if so, do you have a link?
