Landdriver, I'm trying to shut off the loud thump on the JBL premium system. On your post #632 Connectors on the power amp everything you show matches. On the A connector I have 3 other pins,A2 gray,A12 brown and A4 blue. Do you know what they are or where I could find this out? When I run the radio with out the engine running I don't hear It.I tried pulling A1 remote wire and nothing works.

Replying to: redtrack (Oct 11, 2004 6:54 am) Signals present in the harness under the scuff plate relating to the sound system not present in post 632: Wire Color Description gray ACC IN ** shielded blue BEEP shielded brown MUTE Connectors on the power amp behind the back seat not present in post 632: Connector/Pin Description A/2 ACC IN ** A/4 BEEP A/12 MUTE ** Goes to "7.5A RADIO NO. 2" fuse in fuse block in engine compartment. I asked about some of these signals at an auto stereo shop a couple of years ago and the salesperson thought that the MUTE signal instructed the amp to mute itself when someone was placing a cell phone call, and I can't remember what the BEEP is for. The ACC IN line is connected to the battery when the key is in the ACC position. From your description of the problem it almost sounds like your remote input to your aftermarket amp is not functioning at all (is ALWAYS telling your amp to be on), and that maybe the +12V input to your amp is only supplying 12V when the key is in the ON position. If you have a voltmeter you should check that power is always available at the +12V input no matter what position the key is in, and that the remote input is only asserted when the key is in the ACC or ON positions, and the radio is turned on. If this fails to identify the problem, then its possible that maybe I remembered incorrectly as its been a couple of years since I installed my amp, and perhaps it was the A/2 ACC IN line that I connected to the remote input of my aftermarket amp, and not the A/1 line, so you may try connecting the A/2 line to your remote input and see if it rectifies both of the problems. Good luck, and let us know how it turns out. |

There seems to be a limited choice available to upgrade rims from stock to say plus 1 or plus 2 sizing. Tire Rack has only 9 options and none of them appeal. Any web sites out there that people can refer me to or suggestions?

Hi, I posted a long time ago about upgrading my sound system and I was planning to use a line converter to conver the line level inputs to the RCA jacks for hte amplifier. The item I cought was the PAC OEM-2. The instruction on how to hook it up is here: http://www.pac-audio.com/instructions/oem2instr.pdf I was wondering if anyone could help tell me which wires(the ones located on the back of the JBL head unit) goes to which lines on the line converter. Any help is greatly appreciated. One more thing, for those who upgraded their sound system, was there a hole in the firewall you used to pass the power wire from the battery to the inside of the car? Thanks! -William C

Replying to: wwlccp (Nov 01, 2004 2:37 pm) Once again you avail yourself to the vast resources of the Highlander boards, and once again I'm the only one who replies to your question. The following are the pin numbers and wire colors for the harness connecting to the head unit for HLs with the "premium" JBL system: Pin Wire Color Description 1 blue/yellow +12V/constant power * 20 brown GND 3 green/yellow Remote 9 black Line-level FL 8 white Line-level FR 19 red Line-level RL 18 green Line-level RR 16 yellow Line-level common/return 10 bare wire Shield 11 gray ACC IN/switched power ** 17 blue BEEP 7 brown MUTE 13 black/red ANT * Goes to "25A RADIO NO. 1" fuse in fuse block in engine compartment ** Goes to "7.5A RADIO NO. 2" fuse in fuse block in engine compartment Since the JBL head unit already has line-level RCA-level outputs, you don't need the adapter as I was able to connect my JBL head unit directly to my aftermarket amp successfully. However, if you still want to use the adapter for some of its other features (such as the variable level controls), you would use configuration 3 in the OEM-2 instructions as follows: JBL Head Unit OEM-2 Pin(wire color) Wire color 9(black) white/red 8(white) gray/red 19(red) green/red 18(green) violet/red 16(yellow) white/black, gray/black, green/black and violet/black 1(blue/yellow) yellow 11(gray) red 20(brown) black 3(green/yellow) blue/white (I'm not positive about the JBL HU pin 11(gray) to OEM-2 red connection; this is my best guess; this may not be needed by your aftermarket amp). Note that you want to maintain the existing connections to the JBL head unit when tapping into the harness. Hope this helps, let me know if you have any more questions.
