I have a 4-8ga wire, that I wanna connect to a 16 gauge wire. What is the best way to do this? im extending the wire about 10 feet, and its a ground contact, Can I still use the 4-8ga? or should I stick with a lower gauge wire? its for the thermostat ECU harness ground

 

If it's a ground, why do you not just ground it to the chassis at it's closest point.

And what is "I have a 4-8ga wire", is it 4ga or 8ga? 94

 

I have no idea what you're trying to do, or if what you're trying to do is the best way of doing it, but the answer to your question is to strip back a half inch of the insulation on the thick wire, strip off a half inch of insulation from the end of your smaller wire, twist the smaller wire around the bigger wire, then solder and tape. You're going to need about 140 watts to get the soldering iron hot enough for anything thicker than 8 gauge. .032 solder would probably be the easiest, but .040 would work too.

May god rest your soul.

X2,

do you know the whole frame of the car and every piece of metal attached to it is a ground?

you dont need to extend a ground wire. in most cases a ground should be within 1ft of the device you are trying to ground

 

im trying to ground the ECU harness (the thermostat ground) and I dont believe the thermostat is the best location, since it has to pass through the other engine bolts to reach the main ground.

Ill just say 4ga since I have both. But i just want to extend that wire so I can mount it on the frame, or Negative terminal.

I used a multimeter when I did my tests, and found there is less resistance on the sensors grounds, when the main ECU ground location is on the negative terminal

if you want better grounds, just get something like a grounding kit for your car....idk what people think of it but i heard sometimes it helps a lot.

the grounding kit is basically a battery terminal that can accept multiple wires connecting to it. you take the ends of the wires and connect them to your engine and other parts of the engine bay which gives 'fresh' grounds to all of the points you connect them to.

i don't think they cost too much and if u realyl do have bad grounds, it will help your whole car and not just the therm.

 

If that's all you want to do, use the 8ga, make a ground lead that runs from batt. to the same place ECU harness is grounded, use the same "stud" size ring terminal as the harness ground, [but for 8ga cable] and bolt it down with the harness ground, as good a connection as you can get and it will also "beef up" the motors ground. 94
