cntrylvr79 Posted July 28, 2007 Report Share Posted July 28, 2007 Blose or non blose. Oh and hardwiring bad idea. Use a harness. Quote Link to post Share on other sites

amp0804 Posted July 28, 2007 Author Report Share Posted July 28, 2007 I would honestly be glad too if someone can point me in the right direction for the actual CORRECT harness that plugs right into the stock one. I have the harness for the amp ISO already all I need is for the power block ISO Quote Link to post Share on other sites
cntrylvr79 Posted July 29, 2007 Report Share Posted July 29, 2007 70-1787 is what I have listed for the blose symphony in that car. Quote Link to post Share on other sites
amp0804 Posted July 29, 2007 Author Report Share Posted July 29, 2007 Yeah and I had that harness connected and it doesnt work...The pins dont match up Quote Link to post Share on other sites
cntrylvr79 Posted July 29, 2007 Report Share Posted July 29, 2007 which pins Quote Link to post Share on other sites
amp0804 Posted July 29, 2007 Author Report Share Posted July 29, 2007 12v, constant, ground Quote Link to post Share on other sites
cntrylvr79 Posted July 29, 2007 Report Share Posted July 29, 2007 Can you take a picture of the harness in the vehicle. Cause from what I remember of those cars, that's the harness I've used in the past. Quote Link to post Share on other sites
amp0804 Posted July 29, 2007 Author Report Share Posted July 29, 2007 not at this moment car is back at the shop but hold on maybe i can find a picture Quote Link to post Share on other sites
amp0804 Posted July 29, 2007 Author Report Share Posted July 29, 2007 so i cant find a picture but basically there is 2 on the stock harness one of them is a long rectangle which supplies the amped front and rear speakers then the short black one is which carries the constant, the 12v, ground, illumination Quote Link to post Share on other sites
cntrylvr79 Posted July 29, 2007 Report Share Posted July 29, 2007 the black plug has 2 rows of 4 pins each. May not have wire in each location, but there's 8 total holes? Looks something like half of this plug? http://www.installer.com/item/display_i ... it=71-1784 Quote Link to post Share on other sites
amp0804 Posted July 29, 2007 Author Report Share Posted July 29, 2007 yeah its half of that block with i think only 5 wires going into it Quote Link to post Share on other sites
cntrylvr79 Posted July 29, 2007 Report Share Posted July 29, 2007 THen that harness should work for you. Constant and accy may be backwards, but it's the right plug. Quote Link to post Share on other sites
