Original Nissan Titan E-Lock Mod

This modification was originally performed on my Nissan Titan.  I've adapted it to the Frontier
by using the factory service manual for the 2005 Frontier, revision November 2004.
I've received reports from several Frontier owners that this mod works perfectly.

Here's how to wire it on a Frontier:  (Disconnect battery first)

The quick’n’dirty:
Cut the [L] Blue wire at terminal 12 at the diff lock control unit harness.
Cut the [GR] Gray wire at terminal 11 at the diff lock control unit harness.
Strip insulation from [B] Black wire at terminal 3 at the diff lock control unit harness.
Strip insulation from [W/G] White w/Green Stripe wire at terminal 1 at the diff lock control unit harness.

Connect DLCU side of Blue wire to relay terminal 1.
Connect jumper from White w/Green Stripe wire (power) to relay terminal 3.
Connect diff lock solenoid side of Blue wire to relay terminal 5 (diff lock solenoid terminal 4).

Connect DLCU side of Gray wire to relay terminal 2.
Connect jumper from Black wire (ground) to relay terminal 4.
Connect solenoid side of Gray wire to relay terminal 6 (diff lock solenoid terminal 2).

Connect jumper from White w/Green Stripe wire (power) to hot side of rocker switch.
Connect jumper from Black wire (ground) to other side of rocker switch.
Connect jumper from load terminal on rocker switch to relay terminal 7.
Connect jumper from relay terminal 8 to Black wire (ground).
