Please bear with me here as this is a bit of a mammoth post but I want your opinion as to whether you think i'm right much as anything else.
Righto want an alarm and considering what I can get the alarm itself for and compared to the fitted price i'm going to fit it myself.
Not really bothered about the fact that it won't be CAT1 certified just want an alarm that works and it'll give me a nice project to keep me entertained on a saturday.
I'm going for a Cobra 3868 (http://www.cobravehiclesecurity.co.uk/default.asp?docId=12399) nothing fancy just a simple 2 to 1 upgrade jobbie, mainly going for this one because it works off the standard renault plip rather than having to have an extra one.
Got hold of the Cobra fitting instructions and how to program the alarm to recognise the plip etc but the stumbling block i've came across is that the fitting instructions tell me to connect both the negative and the ignition live to the same wire on the UCH loom.
I've got the wiring diagram and pinouts off dialogys which makes it pretty damn straighforward id'ing which wire is wire, now the instructions tell me to connect the ground to A4 on the UCH P202 connector it also says to connect this to the ignition too :S.
Looking at the actual connector and checking with the pinout A4 is the ignition live signal and the ground is B6, now the cobra instructions tell me to connect the ignition to a Yellow/Violet wire which A4 is and the ground to a black wire which B6 is.
What i'm asking is that I assume the Cobra instructions are wrong because there telling me to connect two wires from the alarm to the same wire on the UCH but get the colours right which must be wrong as A4 is certainly not a ground. In my mind I should just be able to connect the ground to B6 on the UCH which is a (the only specific) ground and all should be fine yes ?
Hope I didn't loose you in that mammoth post lol, i'm after opnions as to whether it makes sense to you as much as a definite answer so just post away.
