Installation Help - No Power

[Genin]

Hey, i just joined because i spent a good 5 hours tonight trying to do my first HU installation...to no success. After spending a couple hours wondering how the hell Scorsche expected me to mount my new HU (Pioneer DEH-P3700MP) i finally cram everything in there by notching the plastic bracket and sliding on the clip on mounting screws from my old Delco HU...nothing happens when i hook the battery back up. Car runs fine, all my lights are on...but no response from the new unit. If it helps to know i ended up duct taping the harness together...couldn't find my old soldering iron

Thansk in advance for any help //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

can u start by telling us how u installed it? As in the wires? What did u hook the REM to? Is the ground connected to bare clean metal? Power wire connected?

All i really did was splice the Scorsche/Pioneer harnesses together (like color to like color) with duct tape and plugged it in. I just screwed the ground into the metal screw hole on the chassis of the HU like it was done on my old HU.

considering all of the wires are going to the right ones, it could be that you used DUCT TAPE TO CONNECT THEM. go back and crimp them together using caps.

I would, but i don't own a crimp and it's 11pm //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

go out and buy a pair of crimpers, you will use them more than once in your life.

I know, i had a pair (for Cat5 Cable) but couldn't find it. I figured duct tape would work until i could either find/replace my iron/crimp.

even with duct tape it should work as long as they are twisted together tightly. I do it all the time with other wires. Just twist and wrap em in electrical tape

All i can really think of is the fact that it isn't crimped/soldered and that since the Scorsche kit didn't include new brackets/a way to mount with my factory brackets so i improvised and attached those "clip on" mounting screws to the plastic adapter.

Er, and now that i look, the ground goes from the Scorsche harness and terminates in an unused wire and on the pioneer harness goes from C clip into the HU. Is this right or should the two ground lines be connected or something?

well just think... ur ground from your head unit.. HAS to be grounded... don't ground it to the head unit itself... ground it to a piece of metal so you KNOW it's grounded correctly...

Haha, whoops. Apparently while i was drinking last night i decided that simply interlacing the individual strands of the wires would be good enough. So wrong...so not dirnking tonight when i run out for a new iron. Sorry guys, i'll try again sober before i ask for more help ;P

Let's see here... drinking + duct tape = people like you that keep me in business. Well I guess you have to start somewhere. If the kit did not fit right, then it was the wrong kit that you had as well.

I got the kit from CarDomain. They sent the Scorsche GM1503 without brackets but i need new brackets for it to fit as intended. I went out and got a $3.99 iron and it works fine for now, even if i can't strech my antennae into the back of the HU and my "custom" bmounts keep me from putting the marquee back on.

If you were sent a GM1503 kit without brackets, then someone else had bought that kit and returned it with no brackets or someone had swiped the brackets out of it. That kit is a great kit and comes supplied from Scosche with a crapload of brackets for most vehicles. IF you were anywhere near me, I would give you some brackets. I would give CarDomaon and buzz and have them send you a new kit. A antenna extension is sometimes necessary as well, they can be found at any auto parts store and maybe even Wal-Mart (where that same Scosche kit should be - may be a slightly different model# though).
