mikec Posted January 13, 2013 Share Posted January 13, 2013 My next problem is, I can't figure out how to connect the injector wires together. Obviously I need 1 set of wires to end up as 1 wire To the main relay. Then the the other wires to join into 4 separate wires. I can use piggy back connectors to get it going to test, but I can't figure out how the heat shrink/solder connections are used to replace these. Anyone help on this?

muttleyd Posted January 13, 2013 Share Posted January 13, 2013 Mine was fairly easy as I used the relay board and you have 4 feeds to connect into, so spliced the feeds into pairs an ran 2 pairs of wires back to the board. I guess you do something similar to your relay. You can probably crimp two wires into your relay block, so run 4 wires into a large solder joint with one wire out. Not sure what the injector draw is but others appear to have daisy chained their injectors and its worked. Just preferred to do it in parallel reducing the load. The relay board did make it easy.

mikec Posted January 13, 2013 Author Share Posted January 13, 2013 I've got the relay board, how did you splice them? Is it a case of cutting the insulation off and soldering the wire on? Quote Link to comment Share on other sites More sharing options...
mikec Posted January 14, 2013 Author Share Posted January 14, 2013 Anyone else help me on this. It's the physical side of it I can't get my head round Cheers mike Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 14, 2013 Share Posted January 14, 2013 To join one wire to another without breaking it, strip the insulation at the join point in a band around the wire, strip the wire you are going to join in the normal way, but keep it long, then twist it round the continuous wire until it holds itself in place nicely. Solder together, then cover with heat shrink. Like this, although you can only wrap the 'loose' wire in your case: http://www.instructables.com/id/Master-a-perfect-inline-wire-splice-everytime/#step1 Quote Link to comment Share on other sites More sharing options...
mikec Posted January 14, 2013 Author Share Posted January 14, 2013 Yep I think I know what you mean, and here's me thinking I didn't have to do any soldering best get practising cheers pal Quote Link to comment Share on other sites More sharing options...
muttleyd Posted January 14, 2013 Share Posted January 14, 2013 As bowie says. Was OK I have never liked soldering but its nice and neat. You just need good solder and a decent iron. Good luck. fitting the megasquirt has been easy compared to the other problems I have found. Quote Link to comment Share on other sites More sharing options...
muttleyd Posted January 14, 2013 Share Posted January 14, 2013 Right took a couple of pics. May help Overall shot. Bit blurry. Intend to wrap the cables and add some split sleeve and cable tie it to the fuel rail Wires spliced and heatshrunk Used the wire strip part of this tool to break the insulation around the dia in 2 places half an inch or so apart, then carefully used a Stanley knife to split between them along the wire to expose the copper.
