hornet 570t remote start

I disconnected the two wires going to the lock and unlock from the control module.  Tried the unlock and lock with the wires not hooked up and still popped the fuse.  Inside the fuse holder there is a (-) and a (+) side any idea what these mean?

Please advise also where I can tie in my blue wire going to a 200mA output source?

I disconnected the two wires going to the door locks and tried the remote to unlock doors and blows the 10 amp everytime.  I though my wiring was doing it.

[QUOTE.  Inside the fuse holder there is a (-) and a (+) side any idea what these mean?[/QUOTE]

this is the fused output for parking light polarity,if it keeps blowing when you lock/unlock then you have it placed incorrectly.

only vehicle wire listing on here for yukon is 95-96 and 99 onwards.

if you have a dmm (vital tool for this sort of install) look for possibly a brown wire were your light switch is and meter that wire and see what polarity it is when you manually turn on parking lights.

even after removing lock wires as you said you did the fuse will still blow when you lock/unlock with the remote as the parking lights will flash to indicate the arm/disarm command recieved.if you have set the fuse in the wrong polarity setting in the module then the fuse will blow everytime and eventually pose a risk of causing damage to your vehicles electrical circuit or any modules it goes through.

if in doubt always take the time to test your wires to be sure.

Tony/Howie,

Thanks for your help.  I am headed out to try these changes. 

Thanks again.

Howie,

What is a DEI 451? (relay)? Excuse my ignorance.

Howie,

Don't understand what you mean.  I did change the fuse to set in the + slot and it seems to be fine.  Now changing the white wire to tie in to the brown wire behind the light switch. 

Howie,

Is it possible for me to use a relay instead of the DEI 451?  I have two on hand and wasn't sure or should I go source out the right part tomorrow.  Just trying to finish up.  (The two relays I have are: 12V  20/30A Tyco relays - 5 prong)

If yes then I need some help wiring up relays.  Never used before.

Thanks again for your help.

Is it possible for me to use the diagram below with two relays instead of the DEI 451m?????????

Howie,

I can't thank you enough for all your help.  God bless.

Thanks,

Minor update to Howards Type C lock diagram link above.  Also connect Pin 87 of the right relay ( Unlock ) to +12V.

Here is a link to the DEI 451M Install guide :  https://www.the12volt.com/installbay/file.asp?ID=726
Follow the Type C guide to test and determine correct vehicle connections.

Thanks Kreg357.

Appreciate all your help.

Good Morning,

I have recently installed a HORNET 570T remote start and door lock/unlock in a 1997 GMC Yukon 2/door.  The remote start is working fine but having trouble with the door locks and programming my remote.  I had to add a DEI 451 Micro doorlock relay module. I am indicating that I have Type C door lock circuits. Directly wired (no factory relays) reversing polarity switches???  So I used the wiring diagram "c" that came with the relay.  Tried to activate the doors and I can here the signal in module but the doors are not locking/unlocking.  Is there a way to check to see if I am getting a signal coming out of the module??

When I push on the remote the box (module) receives the signal.  I can here it clicking.  Just not sure how to check if the signal is leaving the box to the doors??and what voltage should I see if any.

*Blue wire indicates a (-) unlock and green wire indicates (-) lock.  I disconnected the plug and tested the blue and green wire with my meter. I engage the remote while still plugged to my meter and get nothing leaving the module?

Info for 2 Door vehicle with Type C locks...

Verify +12V at 451M module side of the 15mp fuse in the Purple,
PURPLE / Black wire.  ( Also verifies fuse. )

Verify +12V output on 451M Module GREEN/ Black wire with Lock command.

Verify +12V output on 451M Module Blue/Black wire with UnLock command.

Another test.  Disconnect the White 3 Pin plug between the 451M and the
Hornet.  Apply +12V to the center Red wire, then briefly ground either
the Blue or Green wire to simulate a lock or unlock command.

One possibility, 451M output wires are reversed on the cut Lock and Unlock
vehicle wire.  The install guide describes the test procedure to identify
the correct wiring connections.

Thanks again Howie and Kreg.  Will try that.
