Default gc8 gearbox sensors / 02 gearbox sensors

so a thing i noticed when runnin the loom through on the racecar on the weekend. The gearbox sensors from the gearbox i got (02 wrx 4.44 gearbox) dont match the 99 gc8 loom i have running through the car

anybody know if i can splice them in? or do i need replacement sensors?

Please Explain?

What sensors? The speedo? If so, just screw in the one that suits your loom.

If you meant the neutral and reverse switches they should be the same, if not just swap them over......

Yeah sorry Doug. Don't have the original sensors from the loom. Replacement box...

The Speedo isn't the same plug, either is the reverse/neutral one.

Can I get replacements to fit or just cut wires?

Don't cut any wires. Cut wires are the enemy of any reliable racecar.

Can you use the sensors from the donor car? All reverse light/neutral/speedo senders are interchangeable between all manual boxes, 5 and 6 speed.

Top pic, middle one goes to the gearbox loom for reverse and neutral switches. Right one is the exhaust sensor in the dump pipe right behind the turbo, left one is rear 02 sensor (not used in your setup)

Bottom pic, right hand plug is the reverse and neutral switches but the wrong plug, you need to get a 4 pin one instead of the 6 pin one. (6 pin socket has two unused that are reserved for DCCD or dual range warning lamp on applicable models)

Small 2 pin on the left of the bottom pic is the speedo but you need to locate the appropriate socket in your loom (not pictured) to see if it's the right sender. There are a couple of different types.

ok, so the middle switch in the first pic was made to fit the right plug in the second pic.

matched up fine but when i attached the power to the car on saturday and put the car in reverse no reverse lights worked?
