Uberoo Posted March 28, 2014 Share Posted March 28, 2014 I decided to remove all unused wires from my 78 Brat.I'm a big fan of making things lighter,and I also don't like having random wires with voltage in them unless they actually do something.First off the brat will have an EJ22, so the wires for the ignition coil on the brat are redundant.Secondly with the EJ22 it will have a nice and powerful internally regulated alternator, so the wires for the external regulator and the factory charging cable for the alt-GONE.I'm not running a horn so its wires-GONE.Same with the radio. So I have those wires cut but there are a few wires I'm not sure about.So lets play Name That Wire!!! (1)First off lets start right where the battery USED to BE. muhaha. I would imagine that the black wire with the dropping resistor can go bye bye, but what is the other black wire. Seeing as I am going to be running an internally regulated alt how much of its connector wire is needed? next up:(2) what is this blue wire by the passenger side firewall? (3)thirdly lets run over to the wiper area.What is this big connector for? (4)This next pic is from the driver side front strut.There is a 4 pin connector and a 2 pin connector.What are they? (5)Finishing up with the engine bay are these green wires not to far from the driver side strut.I'm thinking one of them is for the engine temp but which one? (6)The last pic is under the dash by the speaker.What is this white connector for? Quote Link to comment Share on other sites More sharing options...
Uberoo Posted March 28, 2014 Author Share Posted March 28, 2014 Ok fine. Does anyone happen to have a high quality wiring diagram they could upload? Quote Link to comment Share on other sites More sharing options...
lvsarge Posted March 28, 2014 Share Posted March 28, 2014 I had one for my 1979 somewhere, I'll see if I can find it. Quote Link to comment Share on other sites More sharing options...
lvsarge Posted March 28, 2014 Share Posted March 28, 2014 Though, I wouldn't necessarily call it "high quality" Quote Link to comment Share on other sites More sharing options...
Uberoo Posted March 28, 2014 Author Share Posted March 28, 2014 high enough quality to zoom in and read. Quote Link to comment Share on other sites More sharing options...
lvsarge Posted March 28, 2014 Share Posted March 28, 2014 Nope, sorry... I lost it. If I find it I'll give you a buzz, but I found it on the internet. Quote Link to comment Share on other sites More sharing options...

Uberoo Posted March 29, 2014 Author Share Posted March 29, 2014 #6 is for the heater core fan so not touching that. #5 is for the horns so snip snip.What I thought was the horn was for coolant fan, but its ok that I cut that because the radiator fans will be in the bed on the radiator mounted to a switch. The 2 pin connector in #4 is for the windshield washer so it too will get relocated to the back.No idea what the 4 pin connector is for,its wires are:blue-yellow,blue-green,blue-white,and blue-red. so if anyone knows what its for that would be great. #3 is the intermittent wiper unit if so equipped. Pitty my car just has low and high for the wipers. #2 could be for the choke or the anti-diesel or non of the above.Any ideas on it? Quote Link to comment Share on other sites More sharing options...
RustyBrat Posted March 29, 2014 Share Posted March 29, 2014 i also have a 78 brat specific diagram if you want Quote Link to comment Share on other sites More sharing options...
Uberoo Posted March 29, 2014 Author Share Posted March 29, 2014 (edited) That would be very nice because the 79 has some different components and uses slightly different wiring colors. I gotta admit though I am debating on even running an instrument cluster and just removing all of the various wires for the instrument cluster because: #1 the speedometer is worn out and the needle is erratic and bounces,It will be off even more with the bigger tires. #2 due to the EJ swap I will need an oil pressure gauge + a coolant temp gauge that or do some electrical work to make the EJ senders work with the brats gauges. #3 I wouldn't imagine that the 36 year old gauges are reading accurate anyway. So I was thinking mounting my GPS semi-permanently in a water proof case where the speedometer should go,use one of those $20 gauge kits that comes with voltage/coolant temp/oil pressure and mount that somewhere in the space of the old instrument cluster, then finally run a aftermarket fuel gauge and sender(already have its just collecting dust).Then maybe wire some LED's for the left/right indicators,highbeams,and check engine light. I'm thinking by the time I get done cutting out wires I will be left with like 5 wires inside the dash other than the EJ stuff. Should make solving wiring issues easier.
