how to bench prep rs or alarms

I've done a few rs and alarms. I hear bench prep all the time and whant to know how you guys prep your units. You guys can say I'm new I don't do much alarms or rs but they take me 4 hr I guest for trying to be neat as possible and factory look. Well my question is how do you prep a unit before installing? Thanks for any help.

its bacically cleaning all the wires up typing them all the way rout the wires depending on the location for example i always take my breake wire and my door trigers together in most cases am able to catch them in the kick panel I love to work on nissan toyotas hondas any car that you can unplug the main harnes it makes it so easy to solder and tape them up and make them look factory . take a look at this this is made by murph https://www.subwoofertools.com/downloads/alarm/MurphsPrepDocV1.pdf

I start out by finding all the wires in the car and figuring out where I'm going to mount the brain.  Once I know the exact location I'm going to splice every wire I then open the alarm up and screw it down the bench (or put it in a vice if you don't want to screw it down).

I group all wires that are going to the same location and twist them together with my drill.  I estimate the length needed then add about 6" or so and cut the wires.  I then cover the entire group of wire with Scotch 33+.

I do that with all the wires for the remote start / alarm. 

Then, I install the brain where I had scoped out and route all the wires.  I trim the excessive scrap and solder and tape the connection.

Thank you for the tips. Do you guys hide the brain first and leave the fuses on or do you guys wire it first and then hide it. What's better?

tag all your wires first and then assemble your system on the bench. this enables you to self contain everything (module, harness, relays, bypasses, etc.) it also enables you to eliminate all the extra wires you won't need for your install. this saves a ton of time. have an idea where you will hide the module. cut your wires just long enough to reach each individual tag you made earlier. wire you system on the bench so that all you have to do is grab the system in your hand, walk over to the car and solder or connect everything and tuck the system somewhere underneath the dash. you'll have it installed in 20 minutes.

Sweet I've been doing it the spagetti way so it takes me a while to organize my wire and hide the brain as if its from factory. So that bench prep does cut time I'll have to give it a try.

The following is my ideal procedure:

1. Before you take the alarm/RS out of its packaging and start making a mess, read its manual and the tech sheet for the car, and note the wires you'll need to find. Additionally note where you may need an extra relay, diode, resistor, etc.


2. Disassemble the vehicle to where you can access all the wires you're going to need. For the sake of neatness you want to make connections in as few areas as possible.
More specifically on many vehicles you need only connect wires in 3 locations (the driver's side harness to the rear, the ignition harness, and under the hood). Even if this isn't the case, you still may have a fusebox, BCM, junction block, etc., where you'll be able to connect multiple wires.
Also look for a good location to mount your control module while you're doing your wire search.

3. Once you've figured out which wires you need and where you're going to connect them, take your alarm/RS and all its wiring harnesses to your workbench. Plug the wiring harnesses into the brain, cut the wires you don't need, and group the ones you do according to where they'll be connected on the car. You can use twist ties temporarily for this purpose

4. Solder in the necessary relays/resistors/diodes at this time, as well as any bypasses/other control modules.

5. What I like to do is use Super 33+ to tape any exposed wire, solder joints or other, and then use cheaper tape to wrap the wiring harnesses for neatness.

6. Once that's all done you should have a few small wire groups set up for connection and neatly wrapped harnesses.

Ditto with chriswallace187.  The more time your spend prepping your alarm will result in less time actually spent in the car.  That translates to less time spent on your back, or all twisted under the dash, wondering how to get out without dislocating your shoulder!

...half of the truth can be worse than a lie. <----Roger Russell said that..

I think Chris is spot on especially re 33+ for solder joints and cheaper tape for looming 33+ is about $5 a reel here, also KP why are we twisting cables? Are we worried about explosives or interferance?

Because it is typically the highlight of my day.  I don't always tape up the wires, it depends on the car and the level of security I'm going after.  The twisting allows you to run the bundles through the car easier and cleaner.  Plus, it's just fun.

Fun? OK KP that will do for me. You've made my day which started at 6:66am in at raffic jam. Bench prep? I should be so lucky the trunk of my car /passenger seat are my work benches

i agree with everything that has been said. The only thing i dont do is tape up the wires. Although it works very well, it makes further work/diagnosing to be a royal pita. However you dont want to leave the wires exposed either. What I usually do is use properly sized plastic loom (I always make sure I have multiple sizes/diameters in stock). this way it makes everything very neat, but it also allows for easy removal for diagnosing purposes.
