Hello. I just repaired my firewall to fuelrail ground strap today after having some odd driveability problems and noticing it had broken--
Anyway, FWD sells an upgrade kit made of stinger wire--has anyone here purchased that kit, and where/how does it install?
Looking under the hood I'm seeing the (-) from the battery landed to the block and firewall, the firewall strap I just mentioned, and the one that jumps the PS motor mount. ?
Any info on this would be great, thanks!
I have not personally tried the ones FWDP sells, but I made my own for my Charger using the same wire, soldered lugs for the ends, and quality heat shrink tubing. They've held up for over a decade now, and of all the problems the car has given me, electrical gremlins is not one of them.
Now my Daytona is a different story . . .
I have a set and haven't had any issues. I don't think I used every one of them, but they are nice quality for sure.
Which wires did you guys replace? The one on the PS firewall is obviously an important one. The only others I'm aware of are the ones on the PS motor mount, which has clips, and the two leads that come off of the negative battery terminal/post.
I only did the fuel rail and one from the alternator. I probably should do one from the side motor mount since I have the cable.
I have the FWDP ground kit installed on two cars (SL and GLH Turbo) and they installed and work great. The Stinger wire is very flexible which is nice for routing.
What wires came in the kit for your car, and did you have to do any mods to attach them, or were they all plug-play?
I've asked FWD about this, no reply. I have an oddball wire on my passenger side motor mount that has clips on it versus ring terminals.
Another one I like to do is from the body of the alternator to the engine block, as the alternator itself is isolated by rubber bushings.
Isn't that where the large ground on the head on the driver's side comes from. I know it goes from there to the -bat terminal, but I believe it starts at the alt.?Quote:

Then another from the firewall to the fuel rail hold down bolt.
Look up "the big 3" and you'll see what needs to be replaced. Alternator + to battery +, battery ground to chassis, and engine ground to chassis. Any other grounds help that you can find, like any of those thin braided ground straps.
Can't have enough grounds.
I guess that the early O2 sensors grounded through that metallic exhaust pipe doughnut?

I guess that the early O2 sensors grounded through that metallic exhaust pipe doughnut? Or, they didn't need one?
Actually, it is possible to have too many grounds causing ground loop.

I do this on all my old cars..
I used to play with car stereo stuff. subs amps. yadda yadda.
Obtain 10 foot of 4-8 ga cable.
obtain a dozen ring terminals.
Obtain a click-no-start kit for a 3000gt or fuel pump hot wire kit for the same vehicle.
Install click click no start.. install fuel pump hotwire kit.
create ground from battery to nearest metal frame piece.
redo ground on back of intake to fire wall.
create ground from side mount to timing area.
create ground from top of trans to body.
Create ground from alternator to body.
just makes the whole freaking car run better. sound better.. cant hear the fuel pump whinning with the blinker any more. all sorta nicer stuff.
This is exactly the reason we use "Star grounds" high end electronics especially for Analog signals.Quote:

So, different "potentials" are cause to run grounds to a common spot.
