NP435 backup switch for backup light

[brian72]

What switch to put on NP435 to trigger the backup light? Is it the same one for the duffs 3spd hurst shifter?

Its not the same switch some NP435's dont have a backup light switch. The switch is usually located on the drivers side of the cover just behind the shifter tower.
You can see the red switch location in this link. http://broncograveyard.com/bronco/i-11008_new_process_435_rebuilt_for_eb_swap.htm

Not real sure of any other way to hook up a backup light switch to one that doesnt have one you may need to find a different top cover or just use a manually operated switch.

cant you splice into the NP one to the three speed?

Should be able to. Both have two leads on them. Just hook them up to the 90 deg. spade connections up on the firewall.

I picked up a NP435 backup switch plug and harness that had leads that went all the way up to the coulmn. Plugged right into the stock 3-speed switch plugs.

But that was back when I ran the NP435 and still had the stock harness.

I bought a new switch at NAPA for the NP435, it was less than $10 if I remember correctly (about 3 years ago). The plug to connect it to the wiring harness came from an old EB harness I removed when I installed my Ron Francis wiring kit. The actual plug was the one that went to the brake line H-block (brake line imbalance detection dohicky). It's a perfect fit to the NP435 switch.

Good Luck.

I'm spamming a few NP435 reverse light threads to help someone who may be looking, like I have been doing - the reverse light switch for some NP435's is a Pollak C9TB-15520-B, and Motorcraft replacement part is available

Part Motorcraft SW840

and the pigtail connector

Part Motorcraft WPT826 (which is not cheap!)
