REcently in the process of installing a PAC steering wheel interface for my 04 gen 5 camry i came across a problem in which the SWI wires were receiving a 12v current when the car iginition was ON (accessory was fine however) and traced the wiring back to a relay (4 pin micro Denso) that was located up next to the driver side junction box. It wasn't actually attached to the junction box but rather held onto the chassis next to it with a white clip. The solenoid of the relay was connected to a 12 volt source with the other terminal of the solenoid being spliced into one of the SWI wires with a diode in series. when the mode button was pushed it would cause the wire to ground activating the solenoid and turning the relay on. This would in turn activate the headlights somehow (im guessing it may be connected to the integration relay somehow) . I have got around this problem by removing the 4 pin relay but i feel as if there is something more going on. What exactly is the purpose of this relay and what should the pinouts of it be?

I got three photos. The first one is a close up of the wiring of the relay. The second is the location, next to the brake pedal and the third is of the diode which is attached in series to the solid black wire in the relay.

      Head Unit with Apple CarPlay

      Did you end up getting a head unit for the Rav4? I'm thinking of purchasing one from eBay for my 2015 Rav4.

      RZN169 Poor fuel economy and low/rough idle at cold start up

      Hi all, First time writter. Long term reader. I have a RZN169r 1999 Toyota Hilux 3rzfe Manual 4WD with 425,000KM. Which we have owned from 130,000KM. Since about the 400,000km mark (it had a new/used 138,000km engine only, installed at 385,000KMs) it has been using fuel and idiling rough. I'm getting 100kms less then usual. We would normally get 450-550kms per tank. Now getting 350km-400kms. Our long term mechanic of 20 years retired a few years ago and I have no one in my local area who knows these engines or who I trust. Any sugestions on who I can take my car to? I also have no faith in my local Toyota Dealer. I'm in Sydney NSW. Thank you in advance.

      Purchasing 2014 Prado GXL - Requesting Inputs

      Hello, Thanks for reading my post. We're in the middle of the process of buying 2014 Prado GXL from a private buyer in Brisbane. It has 107K km on the odometer, we arranged an independent inspection and only noticeable issue came out of the inspection is presence of rust. Inspector said general wear (ageing) and rust to the components consistent with the age and mileage. I've attached some of the images(related to rust) from the inspection, please review and let me know if I should be concerned about any future issues or as the inspector mentioned is the rust presence is expected for a 10-year old Prado. Appreciate your help in advance. Thanks, VM

      3rd Gen (XU50) Kluger new aftermarket radio install

      Hi there sorry for the late response, The reverse guidelines are on the factory camera itself (the guidelines are turned off on the Pioneer unit as it doubled up over the factory camera lines) and if I remember correctly they still retain the angle prediction. Everything else (excluding DAB) works***. But instead of using DAB I've downloaded RadioApp which has all of the DAB stations on it and is accessible by Android Auto (not sure on Apple CarPlay though) so no biggie. I also used an adapter to retain the original GPS antenna, works flawlessly. *** EDIT *** The info on the instrument cluster may or may not show, depending on what interface you end up using. In my case I've lost the audio and navigation info on the centre screen and fuel economy/vehicle customisation screens from the factory head unit but I'm not fussed by it as there are other ways to access them on a Kluger. I think it's all retained if you use iDatalink Maestro and a compatible head unit (it will be marked as such) but besides that and DAB all other functions are still operable.

      Removing low beam bulb 2014 Camry

      Thanks, Mate - i'll give it a go. As you say, $15 is better than replacing a damaged headlight (not to mention the aggravation).
