As with most vehicles, the passanger side firewall presents the most viable location to run accessory wiring through. Using a step bit drill in the desired location. To find a desirable location look on both sides of the firewall, engine and passanger compartment to determine the best route. Once the hole is drilled install a rubber gromet, place plastic wire loom around the desired wires to be pass and run them through your rubber gromet.
Any wiring harness that passes through the firewall in a Cirrus will use a grommet. If you are adding a wire, snake the wire with the harness bundle to pass through the firewall.
Sonoma Wire Works was created in 2003.
Through the wire harness bulkhead on the drivers side firewall.
There should be a location where you can go through the firewall where other wires are already there. Piggy back on that hole. If not then just drill a hole through the firewall, being very careful not to drill into any wiring or components. Insert a rubber grommet in the hole to protect the wire, and then the wire.
either drill a hloe thru firewall or use a screwdriver to make a hole in a rubber grommet that is already in firewall. then push wire thru . u dont need a big screwdriver and the rubber will close back around the wire
The lower right side of the firewall. There is a wire harness grommet already there it's tight but I got a 0 gauge wire through by greasing the wire first.
tach signal wire is a blue wire with a black cap that ends on the top of the strut tower near the firewall...done
replace spark plug wires on a 99 sonoma
chartreuse
there is no ground wire it is grounded through the case
there is no specific hole for this. use an existing rubber seal in firewall. take thin screw driver and insert in seal , stretching seal enough to push wire thru. seal will close around wire when you remove screwdriver
My 06 TJ has a rubber plug just under the main wiring cluster coming through the firewall. I just ran the wires through this hole and plugged it back up. Hope that helps!
