Great video. Not a lot of people realize there are 2 relays in a main relay.

Brooooo I remember you from 2004 when I needed. A obd0-obd1 jumper harness Your an o g in the game

Thank you, I always learn a lot from you

Great video, thanks. Especially on the fuel pump relay.

Great video Ryan

Thanks for this video Ryan

thank you so much for this video

Great vid, thanks 💯👍👍👍

Great video and information I did not know. I think my K swap harness is wired for all this but who knows. It is an old car so will buy a spare. Thanks

Great information!

Exactly what I needed to find, Now I get to go out and figure this out on a 93' Accord. New fuel pump, Filter and relay but no fuel pump working. I know the pin 1 power is connected and always hot. Hopefully I'll find it now that I know where and how to look. Thanks for this video

Great content

Thank you very much awesome

Thanks Ryan. This might be my issue. 00 Integra with 07 K20Z3 swap. Cylinder 2 and 4 not firing.

Great video. I've got all of that working as you mentioned in the video but pin 7 (relay to fuel pump). I checked it with the red probe to pin seven and black probe to ground and turned the key on but still no volts reading. Did I do it wrong or I've got a stuffed up relay or something? Thanks

hello, thanks for the video. i have a Del sol vtec turbocharged. it starts perfectly even after parked for long time, but after around 20/30 minutes run i can hear a clicking coming from the relay and the engine hiccups. could this be caused by some old wire or something? thank you

Is it bad if u constantly pull it out to prevent theft ?? And is that relay grounded to the car ? Aski g so i dont have to constantly unscrew it just to pull it...can it just sit lose on side of glove box ??

Hi my Honda Civic 2.2 diesel the year 2007 mk8 is not going to sleep when I drove for less than 10 minutes it seems that the main relay is still energies until I switch the ignition on and off than the main relay will denergies any ideas what cause the main relay to stay energies

Hermano, beautiful video very very well explained,its a first time somebody explained like that.God bless you.

Hi I have Honda civic mb 2000 model my fuel pump no power.even no power in number 7 wire.i check all fues is OK.please tell me what I check.

I have a 2002 honda civic lx 1.7 with the key in the on position not cranking just on , the fuel pump stays priming and wont shut off, any ideas if it might be the main relay ..? Ive checked the blue relay and brown relay behind the glove compartment and they seem to be doing their job , please help

Thanks for telling us what to do when we order a new harness and it doesn’t come with a main relay plug 😢

Hi is the immobiliser built in the main relay as well. Lost all the keys. Cut a blade/key, but won't start car. Do you know if a HONDA ACCORD 1992, 2.2, has immobiliser module. If so do you know where the immobiliser unit will be. Thanks.

My 97 civic when I try to start it the horn blows and I have no power going to the starter what would cause that

I just finished the swap on my 99 dx.. however I am not getting any power to wire #3 with ignition on.. with ignition off it has continuity as well with ignition on but no power.. ignition switch has power to all wires, main relay is good, ecu is good.. they have been tested on a different car.. I have 3 grounds on engine bay (transmission case, valve cover, and intake manifold) fuses are all good.. I’m am running the Rywire budget harness V2 with the Hybrid Racing conversion harness.. any ideas?

Hey bro name is ronnie. I have a 2001 Honda odyssey with the main clicking.im getting gas to fuel rail but no spark from plug. Help me please

Merci monsieur...Traduction en français..Is it the same process for a Honda jazz 2005 ..I have the same problem.Can you help me Sir. MERCI Monsieur.. How to find this swith and where is it situated..Merci... Watching from France... Monsieur..

My 98 v6 dont start I have another accord 02 and try the main relay and work on the 02.

My PIN 3 is not getting power? i been all over the place and can't find anything.

Thank you

Do you know what could cause #6 to have no power during an attempt to start. All other slot tests match your video.

97 ek gsr swap Rywire harness I’m getting 12v thermostat ground/main relay ground/driver side shock tower ground HELP ME PLEASE!!!

My PIN 2 is only getting 2.5 volts can anyone help?

Wish you make one with ef model

i have a 95 Civic Coupe. Hope I won't need to replace the relay anytime soon.

👍🏻👍🏻👍🏻

I'm not getting a beep on the black wire

If I were to convert this to a 4 or 5 pin relay how would I do that?

If I use a rywire harness to obd1 convert my EF (sticking with the stock engine), will I need to change my main relay to the later pinout too?

I have a 98 Honda Accord DX and my slot three on the main relay actually has two yellow wires positive and negative identified or what has a straight one doesn't but they're both yellow and there's definitely two wires

Thanks Ryan! This should help sort out intermittent no start.

I did the test for ground and I didn’t have no beeping sound, I don’t know what else to do, my ecu is not turning on and my fuel pump is not activating and im not having check engine light on the dash, I even bough a new relay from jdi company and I still have no power on the ecu

There are a few companies now that make a Honda main relay adaptor harness to convert it to a regular automotive relay.

Could you show us how to replace that relay with a regular relay?

U are the fucking man fixed my car 🙏🏾🙏🏾

The main fuse goes wild with clicks when I'm trying to start it

Could this relay be part of a no crank no start situation?

How if don't have power on the white wire

Well not on the older Hondas they're under the steering column under the steering wheel

Just swap my rsx it only cranks no start all grounds connected

Thus I'm having a starting issue

Need some help

Hell I might be able to drive my car again
