Currently working on this and not sure what to try next.
2002 ranger 4.0 auto 4x4

Loud clicking behind dash even with keys removed. Only response from key turn in ignition is in turn over position, clicking stops and no response from electronics or starter. None of the electronics are working at all. Theft light blinking an differating speeds.

Ive pulled out the ignition switch but it still keeps clicking with same symptoms. I isolated the clicking to a black box containing a blue plug and a few black ones below and to the right of the steering wheel. Im assuming they are all relays. The blue one appears to be for my blinkers and thats all i could find on the internet.

Im out of my league here any advice or steps to try next? I thought about pulling the relays out but they are in there pretty good, afraid of tugging to hard.

Thanks for any help in advance.

Edit: i keep the negative cable disconnected when working on it and to stop clicking.

So i found out its called the auxillery relay box, has horn, lamp, windows relays etc... i pulled a few relays out. The battery saver relay i pulled out and the rapid loud clicking stopped. A faint clicking noise is coming from my passenger side air vent now. Possibly originating from the blower motor? I have no idea whats going on. Im not good at solving electrical issues, any ideas?

Problem has been found. My brother came over and we started unplugging electrical stuff and noticed the more we unplugged, the more stuff started to work. Every time we pushed the brake in or turned on the head lights we noticed everything would stop working, even the clicking noise stopped. When i unplugged relays the new clicking was from the blower motor trying to engage. We realized it didnt have enough power to draw from. Battery tested ok and we put it back in and tsame problem. We changed the negative contact and no luck. Jiggled the power wire and lights turned on for a split second. Turns out the positive wire cable has a bad bungle spot that we have to replace, it gets a good connection when its held a certain way, prolly knocked it loose hitting a bump.

Short answer: power draw issue, was able to find this out by disabling electronics via relays and fuses. Replaced corroded negative contact and found a bad taped bungle down positive wiring that needs replaced. Hope this helps someone.

Thanks for posting the "Solution". Bad battery connections cause a multitude of problems.
