93 range rover classic. can anyone tell me where to get or how to make/replace the twin white wire that comes off the negative side of the ignition coil and splits to i assume the ecu . it has an in line black nodule that when uncovered looks like a built in resistor that then leads to i think the power supply to the fuel pump (two black wires bolted to the fender) the two white wires are no more than 5" long and the lead after the resistor is only say 2" long. i am having ignition problems and using the guidelines in the manual have traced it to a wiring problem. i would like to replace this wiring to see if this helps but can find no one or mention of what it actully is. thanks.
