SO i decided to stick with the wiring project in case i never came back to it at all. I don't know about others that have put the OEM harness on a diet, but it has been a pain in the arse from the start for me, and i enjoy getting into wiring! Trying to work out what extra was going to be trimmed out & seeing all of the multiple piggybacks in there from 20 years of "technicians" brought me to a bold conclusion. In the event that there are youngsters reading I won't repeat what that conclusion word was.
I can tell you it rhymed with
BUCKET! What better way to learn the system & have it fit exactly the way i want it to than to build it myself. T some that may sound daunting - but i got the sense it would be a LOT easier than messing with the sticky rats nest.
First step - Identify all of the components & plugs that would be needed, and then cut them off
Second - Pull up the factory harness drawings & print the ones i would need to iden ify the wires. I have the manual on PDF, but i find it easier to use a paper drawing in front of me. Then, just label away.
Basically just did that for every plug / sensor / component that i would use & then took it out to the garage.
I left enough on each plug to stretch to where it would need to connect for the trial run - With not having a bulkhead in place yet i couldn't cut the wires to size. Using zip ties I secured everything to the frame close to each other, and then joined everything together using terminal boards & crimps following the factory layout schematic minus the crap.
A keen eye will notice that there are no light circuits in there yet. As this was more about getting the motor running i decided to do those at a later date.
I'm also currently using the oem fuse & relay boxes - but there are so many circuits in them no longer being used that i have decided to ditch them & build my own relay & fuse board.
The moment of truth - would it work or go up in flames.....If i'm honest, i was expecting a little bit of smoke
I turned the key, heard a relay & then she turned over, and over, and over, and over...........mmmmmmmmmmmm? Fuel line has pressurized, Ignition's live......Crap - did i mess up the belt job??
Started to wonder what i had done wrong this time....and then it became obvious.........OMG - What a moron! I looked over at the workbench to see the ECU waving at me!
Let's plug that in shall we.
The open header roar the second i turned the key put a monstrous smile on my face. The gauges were working, it was running smooth & i was a happy man.
In all i put about 8- 10 hours into the job. I figure cutting it down & trunking everything neatly will put another 5 - 8 hrs on top of that. I don't think that's bad at all taking into account the time i put in originally just trying to trim it down & keep it working. I would definitely recommend this method to any builder out there. Minimal harness, fairly easy to do & you will know the circuits perfectly for future reference.
I will be editing the schematics when i get free time & making them to represent how the harness is layed out. Once they are done I have no problems whatsoever sending them out to anyone who is interested in going this route.
I've had 5 gal of petrol in the tank now for over a week. No signs of a leak yet. The Type-B fuel hoses i put on will have to go though in favor of some rubber Type-A - the inner sleeve is too firm & I'm not happy with how secure they are on the lines. I think next i'm going to start making the scuttle so that i get the main wiring tidied up & in place while it's still fresh in my mind.
